I've had a subscription to flexjobs and it was worth the money, but most of the jobs are for people who already have some sort of specific qualifications or degree. If you don't fall into that category it might not be worth your time.

www.realwaystoearnmoneyonline.com sends out a newsletter every so often with work at home job leads, and they have a lot of the same things that I found on flexjobs, plus more. The site also splits jobs into categories, such as phone and non-phone jobs, to help you narrow the search as far as what you want to do.

Also, if you're looking into transcription, you can start at https://workshop.castingwords.com with no entrance test. How it works is you get paid very little while you learn the ropes, and then if you're good at it, you work your way up to a better pay grade. I've done it and made decent money for part time flexible work. At first I thought it was a scam because the pay was so low, but I kept with it and worked my way up. There's not enough work for it to be a full time job. I also wouldn't suggest getting too far into it without getting a foot pedal and the accompanying software. I have stopped doing transcribing for now because the company was pretty picky about what they would accept and I ended up wasting a lot of time trying to find files that weren't crappy audio so I wouldn't have to stop halfway through.

Medical coding is a good job to do from home and you can either go to college or take a non-college online course to learn how to do it. All the jobs I've seen for medical coders are 40 hour a week jobs.

Wishing you good luck.
