Coder to write Rapid Fire Software for XBOX 360 Microchips

I need a programmer to write code for a PIC12F683 Microchip. The Chip will be fitted in a xbox 360 controller and used to make the programmer rapid fire. The chip will be wired into certain points on the xbox controller circuit board in order to make the controller have new modes/turn rapid fire on guns such as pistols etc. It may seem complicated, but please PM me for more details. Hex codes will need to be written. Regards, Henry
