Hey there anon. I've never hired off of these sites, but I've looked at them for jobs:
http://indeed.com
http://careers.stackoverflow.com/

I don't know if there are fees to pay or anything, but indeed seems to take a lot of cross-listings.

Other than that, if you know some C.S. students, we're generally looking for work to build up our portfolios, but depending on where you're asking, you may get shite quality.

Http:\\www.dice.Com is a good place to look as well!

Where are you located?

Step 1: Know how to write the code you need written yourself.

Step 2: Ask your applicants to solve a problem in whatever language you need them to write in a coding interview to last not longer than 1 hour.

Step 3: If they pass the coding interview, hire them.

Step 3 will take you a while to get to, as finding good programmers is a hard task indeed.
