Elance takes some getting used to. You have to learn how to write a great proposal. Some people are just going for cheap crap, but there are real customers there and part of the game is finding and identifying who the real players are. There are plenty of $1/article jobs but those are just crappy junk jobs that noobs take.
I do pretty well, but I make it a goal to do 3-5 proposals per day and I might get maybe 5-7 jobs a week if I'm lucky. That's a lot of "NO" and losing to other people before I see a job come through and that's also actually doing the work and talking back and forth with people. Some people want to talk to you and have this big back and forth and you have to know when to cut them off or they will eat up your time.
I have often thought of writing a short guide to it because Elance has a huge learning curve. There are farmers there with huge teams, but it's different when you're a solo act.
