You can ask for a non-disclosure agreement feature at rentacoder, With this your bidder has to sign an agreement with you for full secrecy. check this: www dot rentacoder dot com/RentACoder/SoftwareBuyers/FAQ.asp#nda
I've had great experiences with rentacoder. You can check a box during the project creation process which specifies that they must sign NDA to even look at your project.
