Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.

Other opportunities are easier to get but not nearly as lucrative. Many market research companies have video-watching verticals through which participants can earn points for each view. Swagbucks and InboxDollars are two legitimate options. You can earn points with them, which you can redeem for gift cards and occasionally cash. The hourly rates working out to less than minimum wage in most cases but aren’t bad for a few spare minutes of your time here and there.
Cleaning and Damage. Online rental platforms let you charge cleaning fees so that you aren’t financially on the hook for the full cost of a post-tenant professional cleaning. Most cover the cost of renter-caused damage too, provided you properly document and report it. But financial redress only goes so far. You still have to deal with the inevitable investment of time and energy to fix the damage or clean up the mess.
Bootstrap: This means you’ll be self-funding your business. While not everyone will have the funds to pay for everything they need to start a startup, bootstrapping means that you retain 100% control over your company. You’ll be using the financial tools you have at your disposal—whether that’s financing your business growth with credit cards, personal loans, traditional business loans or a home equity line of credit. The payoff if you can bootstrap your company to an exit or IPO though, is that you might not ever have to work another day in your life.

In 2017, there were almost 90 million pet dogs in the US. Which has opened up a huge opportunity to make money online as a dog watcher or sitter. Specialized sites like Rover or Care.com connect pet owners with pet walkers, sitters, and boarding houses to help look after their best friends when they’re at work or on a trip. If you’re an animal lover, you can make extra money and get to spend some quality time with a furry friend.
18. CraigsList – Some things don’t ship very well. Other things may make you feel uncomfortable to sell to someone across the country. Anytime you’re selling a large item or something you just don’t want to ship, Craigslist is a great place to go. It’s simple to list your item (again, take good pictures!). If you don’t like the idea of putting your phone number out there, the interested individual can send you a message to your inbox without even getting your email address.
Instead, go with a self-hosted site (like my blog here is)—this means your blog will be hosted on your own server and you’ll have full control over it. There are tons of highly reputable, affordable companies you can choose a web hosting plan with to get your website online, like Bluehost, A2 Hosting, Dreamhost or one of these monthly web hosting services.
Research selling prices of items similar to yours. Look up completed sales or current listings of items similar to yours. Find the high- and low-end prices, and price your object around the median price level. If you want your item to sell quickly, price it at the low end. The condition of the item also affects the price. Items in poorer condition should be priced at the lower end. Also, consider how many listings there already are of items similar to yours. If many similar items will be competing with yours, you may have to set the price lower to get the sale.[22]
Seek a payday loan or title loan as a last resort. Companies that offer payday and title loan services offer high interest rates (sometimes with percentages in the hundreds). If you cannot pay the loan and any interest back within the stated timeline, you risk even higher interest costs or, in the case of a title loan, the loss of your car. Avoid these types of loans in all but the direst circumstances, unless you are certain you will be able to pay the loan back.
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.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)

If you’ve got experience and expertise in a specific area of business, there are hundreds if not thousands of business owners who would love to jump on a phone call and pick your brain. This can be an easy way to make extra money online and to hone your skills to use in your consulting or freelance business. Sites like Clarity.fm let you create a profile where entrepreneurs and business owners can pre-pay to book a phone call with you for a set amount of time. Whether you’re an expert in raising money for startups, building apps, or running a restaurant, you can make extra money selling a few minutes of your time to people in need.

That would be retail arbitrage, one of the top careers for self-employed introverts. Practitioners of retail arbitrage buy products for pennies on the dollar at auctions, from online retailers, even at garage and yard sales, and then sell them online at sometimes-substantial markups. Fulfillment by Amazon (FBA) is the most popular platform for U.S. sellers, but other options work too. Learn the FBA ropes with this low-cost Udemy course.
