I'd be worried about legal ownership issues with this. If someone just writes code for you and says, "Here you go, it's free" I'm not sure that would really work. There has to be a contract in place (right?), and can contracts be "for free"? I guess this could be structured as an internship, but I read here awhile ago that those are being cracked down upon in the US.
Here's one idea: Have ehansul write and open source code that would be helpful to you. That way there are no ownership issues.
I don't see any problems having contracts which do not enable any compensation for the party doing something. And even many FOSS projects want copyright waivers (I think that's the term) for any patches they receive.
