Wish I knew. I don't even have a job.
I think some people have had success driving for Uber. Some do it full-time, from what I hear. But I don't know... it probably depends on where you live. (I take it your auto-insurance would probably go up by a lot too. And you need to pay for gas, and the mileage on your car. I think it could backfire.)
One thing that does NOT work (at least it didn't work when I tried it) is audio transcription. It's a legitimate job (not a scam), but it's way too time-consuming. (After calculating my pay per hour of work, I found that it was well below minimum wage. Unless your hearing and memory are very good, and you type very fast... and even then, it's still probably less than minimum wage. Medical transcription pays slightly higher, but I doubt it's much better. And you need to be familiar with medical terms and drug names and stuff.)
Another thing that I've tried, that does NOT work, is doing crowdsourced work collecting data for market research. (You go around to stores and use your smartphone to discreetly take photographs of the shelves and what's on the shelves, and sometimes get the UPCs or other information, being careful that nobody sees you.) Problem is, I think if you use a car to drive from place to place then it probably costs more in gas than you're getting paid. On top of that, I question whether it's even legal... these stores are private property, after all. Seems like trespassing, to enter the store and inspect the items, without having any intention of buying anything. (A number of times the management caught me doing it and told me to stop... sometimes they even asked me to leave the store... one shop owner got very upset and told me he was calling the cops. And I completely understand. For all the store manager knows, I might be planning a robbery or something.) It can also be time-consuming depending on what photos/info the client wants you to collect.
