How much *Python script*

How much would somebody charge for
A xbox 360 sensitivity python script, you can notice in my game
i have a resident evil style approach. When i tilt my right axis half
way i want it to move at half speed, when fully tilted i want it too
go full speed AIMING.

I want to be able to link my Joystick right axis “Up, down, left, right”
to it.

Please let me know, no daft prices please.
