Making Android phone a Joystick for computer games.

I have an HTC ANDROID phone. I want to convert my phone into a JOYSTICK when playing games on computer. The game will be played on computer and my ANDROID phone will be used as a joystick. For example: If I am playing a racing game and I turn my phone towards right, then the car/bike should turn right and so on....! <BR><BR> Kindly send me your bids with complete details of HOW YOU WILL PROCEED WITH PHONE-COMPUTER CONNECTIVITY? HOW WILL YOU HOOK THE KEYBOARD FOR MAKING THE PHONE AS A JOYSTICK? Also tell me how many days will this work need to be completed?
