I never thought I'd make money as a writer, I'd almost given up, and then I found InteractMedia. It's Copy, but it's writing (if you can write creatively, you can write copy, copy is EASY). They have a small audition process (including picking three "specialties" on their sister site YoExpert) and rate you based on your sample (which you have to come up with from scratch from one of your three specialties - so do REALLY well on this one). The higher your rating, the more jobs you have access to, and you can improve your rating if clients rate you higher. You pick and choose your jobs.
I couldn't be happier with it, in my first week there I got someone adding me to their favorites and the next thing I know they're offering me this massive (well-paid) direct assignment. InteractMedia takes 20% commission off of what you earn, and they pay out twice a month after you've hit $20 for the pay period.
Hope that helps!
