Where can I find someone to create a really simple software program for me?

I'm looking for someone who will create a piece of software for me. Just a simple program with one purpose, one task to execute, single user, no pretty UI, in fact, it may be possible to achieve with just a registry edit, but I don't know. Is there somewhere online budding young software developers hang out looking for ways to expand and improve their skills or somewhere people bid on jobs like mine? Thanks.
