Ask HN: Any tips for hiring a freelance programmer?

Hey guys,

Traditionally I've done all of the programming on my personal business projects. However, I'm getting to the point where I'd like to start out-sourcing some of the work to freelance programmers.

How do you guys go about finding programmers? My project and budget aren't large enough to warrant the hiring of a software development shop. I'm really just looking for one or two developers to put do 50 to 100 hours of work.

Any tips would be greatly appreciated.
