Xbox controller fix?

I have limited the use of my left hand, which can make playing videogames a little tricky. So I use the adrenaline stick for Xbox as my main controller. It's a joystick so it makes playing games with one hand a little easier. Unfortunately the Company does not manufacture it any more and that figure has broken on it yet again. Does anyone know of a place or web site that does controller repairs? (It seems like a pretty easy fix, it's just a little plastic piece and a spring in the trigger)

Also I am done many web searches and they can find anywhere but actually still sells it. If anyone has any idea where I may be able to purchase a new one please let me know.
