Ask HN: Where do you look for PT/contract work?

Hi HN, sorry if the question has been asked before, I'm kind of new here. I'm wondering where you (i.e. reader of HN) go to find part-time or contract work. I have been hiring using odesk, elance, rentacoder, and guru, but generally speaking I've only found average designers and coders, not the "look at the web app that I made over the weekend" type of people.

Any help? Thanks
