Creating an online downloadable multiplayer game

I have a concept for an online multiplayer game which would require the user to download a lobby interface to access the online content. I am looking for advice for where to look for people who would be able to write this software.Also how do I go about protecting my idea.

Thanks

All you really need to do is find a freelance site for developers. I would at oDesk, Guru, ScriptLance and Elance. If you need somebody local, you can always check Craigslist, although the more specialized help you need the less likely you will find the quality on Craigslist.

To protect your idea, I would just be as vague as possible in public areas and let the developers know more about the idea if they email/message you.
