You can try working at oDesk. It's free to join and they offer guaranteed pay for hourly rate jobs. Just make sure that you're logging your hours correctly when you're working with a specific employer.
I've been working at oDesk fulltime for a year now. So far so good... I'm earning more than what I earned from my office job. :) I'm earning at least $300 per week and I know a lot of people who earn more than what I do.
