Ask HN: Where could I find a Ruby developer to make a prototype?

I am currently looking for a Ruby developer to make a prototype and not entirely sure where to look. A freelancer (>$30/hr) is a bit out of the price range. I am looking for somebody who has great communication skills, possibly a student looking for a paid internship or one with some free time? I have heard some not so great things about the rent-a-coder sites and was hoping that the HN community could help me out. Any help would be greatly appreciated.

Thanks a ton!
