I recently joined Toptal and was shocked to have my rate set at $30/hour. I got them to raise it to $40/hour, but that's still nowhere near what I was earning working as an independent contractor or even what I can get on Elance.
Just don't play "I have lower price" game, be professional and you'll find a lot of jobs. See my profile: https://www.upwork.com/users/~01d95397aacaef6e88 (Elance soon will me merged into Upwork).
