Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs.
@Philip Taylor So by what you’re saying, I can be an unaccredited doctor or surgeon for someone (for example) but do it at a much lower rate than the accredited doctors and surgeons. Since I know what a scalpel is and I wear rubber gloves, I’m a doctor. So, I don’t have to have to respect the profession of medical science at all since I think I know what I’m doing and just go for it.
If you have specific writing/journalism skills or are adept in various IT/software domains, freelancing may prove to be a lucrative source of secondary income. Increasingly, companies are implementing a content marketing strategy and turning to outside sources for specific assignments, and if you can prove your worth there will be more work available. Even simple skills like data entry may be to your liking, provide you can offer at least 5-10 hours weekly.
Tutor students. If you have an academic specialty and can squeeze in a couple of hours during the week while Junior is taking a nap or Janie is at gymnastics, share your knowledge with struggling students. Find students looking to improve their grades on your own through your kids' schools – check a site such as Craigslist.org to gauge hourly rates in your area – or sign on with an online tutoring company, such as Tutor.com. You must be available to tutor at least five hours a week and have a college degree to tutor certain subjects for Tutor.com. Tutoring is done virtually from home via a computer, not in person. Tutor.com tutors are paid an hourly rate based on the subject.
A spin-off for web designers is to offer a landing page creation service. Well optimized landing pages can be the difference between a successful and a failing business. And, as creating the perfect landing page isn’t easy, this is a service many businesses are prepared to pay for. I know people who are earning 6 figures per year and all they do is create landing pages for businesses. There’s serious money to be made.
Many people fancy themselves as designers. If you have a unique idea for a new product then it may be time to get it designed. This can be a long process involving prototypes, discussions with factories, package design, and much more. However, the profits once the product is on the market could be substantial. And remember, with Amazon FBA, your products can all be stored and shipped by Amazon, giving you time to think up your next invention.

Similar to writing reviews, you can become a freelance writer and make extra money writing articles and website copy. While you don't have to be a professional journalist to write for a website, it helps if you've blogged or had your own website where you blog regularly. Even better is showing that you have some experience in the niche in which you're trying to find a job.
Like writing (above) transcription is another type of work that often equals a full-time income. However, there are lots of sites that accept beginners that don't pay very much for the audio transcribed. While a professional transcriber may not bother with the sites below, someone without the skill to be a professional could use them here and there for some quick extra cash:
Even if your car rarely goes unused long enough to rent it out to a visiting driver, you can still potentially “rent it out” by turning your vehicle into a rolling advertisement. The site freecarmedia.com pairs car owners with advertisers who are looking for mobile billboards. Drivers can earn up to $400 per month by agreeing to have their vehicle wrapped with a vinyl decal (called a car wrap) provided by an advertiser. Generally, your program will last anywhere from 6 to 24 months, and you get paid for following your normal driving routine.
Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online.
Matched Betting (not available in the USA) enables you to gamble (nearly) risk-free. I say nearly as there is always room for error! It involves placing bets on all outcomes of an event, using free online bets given out by the Bookies. Although it may take a while to get your head around the concept, Matched Betting can make a substantial addition to your monthly income.
Online savings accounts usually come with crazy good interest rates to help you grow your money faster (regular in-person banks can’t offer rates as high). We’re fans of CIT Bank and Discover Bank (among others) because their interest rates are often over 25 times the national average. That means the money in your savings account will grow 25 times faster than the pace it’s most likely growing at now. Really, though, you can’t go wrong with pretty much any online savings account that offers over 1.50% APY 🙂
