[help] Toy Car Remote Control via Cell Phone Bluetooth / Computer Bluetooth

[iamsam]

I'm doing a project, a part of it is using bluetooth from cell phone to control the toy car.
For the receiver, I'm still finding the Low-cost bluetooth module, below $10.
Any suggestion?
I know that there are a lots USB bluetooth module which below $5, but I have not idea how to read and decode the USB signal by using 8051, thanks!!!!
