Ok so I have several years web design/dev agency experience and want to start working freelance, eventually fulltime.

What are some good sites where you can bid on bigger company web projects? There are dozens of freelance sites with low budget projects and low talent designers/devs to bid on them. (Not to sound rude but really who works for $10/hr.) Anyway, what are some good sources to start bidding on web projects?

Thanks
