Ask HN: What is the best way to find freelance devs?

I'm in need of a freelance iOS dev (or two) in the Southern California area. Anywhere on the West Coast could work as well. W

hat is a good way of finding great freelance devs?

9/10 devs I speak to say they can do everything and can't do crap. Just nonsense.

Have tried traditional channels of ODesk, ELance but nothing but crap on there as well.

Meetups - no go here in SoCal, everyone has an "idea" and is coming from a restaurant waiter background. The scene is pathetic.
