Great list! I have another to consider that I personally have 35+ years experience providing. Clean up litter outside commercial properties on foot using inexpensive hand tools. It’s almost as easy to do as going for a walk! I started doing this as a side gig in 1981 and soon grew it into a profitable full-time business. I share my experience in my book, Cleanlots.
A large proportion of homeowners and small businesses have lawns to tend to. Many turn to independent providers of yard work services to take care of their lawn care woes. To start and sustain a yard work services side business idea, you need training, equipment, and a growing network of customers. In the U.S., a full-time landscaping and groundskeeping worker reportedly earns a median wage of around $25,000, while those working on this as a side business idea largely during evenings and weekends can expect to make substantially less.
If you don’t mind doing other people’s chores, then TaskRabbit is a great option for making money online. Earn extra income by walking your neighbor’s dog or mowing Mr. Smith’s lawn. It might seem like not the most lucrative option, but the top taskers reportedly earn as much as $7000 a month, making this a full-time way to make money online for some.
It’s not very engaging, or mentally stimulating, but taking online surveys through companies like Survey Junkie do pay out (a little), believe it or not. Even if the payouts come in the form of Amazon gift cards, sites like Swagbucks can pay well. Just don't expect to make bank with this side business idea—I recommend combining it with another source of side income from this list of my best business ideas, and turning to surveys in your downtime when you need a little extra income.
Test websites. Remote usability testing means getting paid to navigate a website for the first time and giving feedback to the website owner. Most tests take approximately 15 minutes, and you can get paid up to $10 for each test. A test involves performing a scenario on the client’s website and recording yourself doing it. For example, you might be asked to go through the process of selecting and purchasing an item on a retailer’s website.
"To hackers who make a living stealing information from unsecured computers and network connections, the teleworker could be an open the door to the organization’s most sensitive data. Security and privacy have become increasingly rare commodities these days thanks to the ability of hackers to stay one step ahead of just about every security measure that technicians can create. Security breaches are a significant enough threat in a standard office environment; however, when an organization has employees working from home or on the go, these risks become even greater.
Expertise is another matter, but remember that writing can take many forms—from resumes to news articles to marketing materials and even thank-you notes. (You can even write for businesstown.com, although that gig doesn’t pay … yet.) There’s probably some form of writing you’re qualified to do. Plus, if you’re good enough with grammar and punctuation, companies will pay you to be a freelance editor. One friend made good money editing posts on a popular travel site.
To do that, you have to harbor a few fundamental guiding principles in your mind. Today, if you're at all serious about generating a full-time income (and more) from your online activities, then you need to focus on passive income as opposed to active income. Sure, the active income will help you survive. That's the scarcity mentality at play. But it's the passive income ideas that will help you thrive.
There’s more to being a coach or personal trainer than just being fit and loving to exercise. Finding a specialization is important, and licenses might be required for certain types of coaching roles. For instance, a friend in Boston obtained US and European soccer-coaching licenses before opening a successful one-on-one soccer-instruction business.
As a result of these and other factors, an estimated 40 million Americans now work from their homes. This number includes employees working from home for a larger employer as well as self-employed. Not surprisingly, two-thirds of home-based business owners are women, who choose this option either because of childcare concerns or because of a perceived glass ceiling limiting their earnings potential in the corporate world. Running a business out of the home offers a number of advantages, including time savings, control over working hours and conditions, independence, and flexibility. Starting a home-based business is also considerably cheaper than starting a business in rented facilities. In addition to saving money on overhead expenses, commuting costs, and wardrobe expenditures, many home-based business owners can deduct a portion of their rent or mortgage interest from their personal income taxes.
Every year, hundreds of millions of documents are notarized in the United States: wills, mortgages, citizenship forms, handgun applications. While for decades, this has all been done in person, there is a budding crop of sites that allow notaries to take their services online. If you’re already a notary, you can sell your services online. Or, if you want to get started, check out the National Notary’s checklist for becoming a certified notary.
Since time is the most precious commodity on this earth, invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop. It's obvious that this is the preferred route, but clearly the road less traveled.
Now, I know what you’re thinking. Most of the software and apps you use on a regular basis are made by massive companies or established development studios. Well, yes. But many successful apps, particularly those in the Apple and Google stores, are created and marketed by individuals and small businesses. In fact, independent developers made $20 billion in the App Store in 2016 alone.
I overheard my wife talking to a homeschool mom that raises and sells a certain type of dog (a registered breed of some kind) ranging from $1,000 to $1,800. I also know a couple teens that started a bread business where they sell the product at the local famer’s market and local stores. The product(s) have been so successful, most of the family has been involved in it.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Matt Collar from AllMusic described "Work from Home" as one of the "most playful tracks" from 7/27 writing that said song along with "Not That Kinda Girl" "build upon Fifth Harmony's knack for mixing juicy R&B hooks with just enough hip-hop muscle to keep things from getting too polite." Maeve McDemortt from USA Today agreed, citing it as a highlight and praising its production. The Boston Globe's writer Maura Johnston called it an "Afternoon Delight", similarly, Brittany Spanks from Rolling Stone described it as "an "Afternoon Delight" for the smartphone generation that fluttered by on minimalist synths." Carolyn Menyes of Music Times gave it a positive review, noting the "chilled out vibe" and the "chorus that cools down the song's momentum rather than pumping it up".
Find work. When you first start out, you may have to accept work writing about a topic you don’t find all that interesting. You must keep an open mind and be willing to accept work that may not be in your desired field. However, as you continue to write, you not only learn about more topics, but you also build your reputation. With time, you can be choosier about assignments you want to accept.
