oDesk is the best legitimate online job site available nowadays. Not to mention the fact that they offer guaranteed payment for hourly rate jobs.
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.
