There's actually no soldering involved so I might just attempt it myself. If I fail I will be coming by haha.

Its pretty easy to install, just make sure you don't cross the wires up. Like me i did and it wouldn't clamp on the ECU correctly. I was pretty frustrated but i emailed mike at burger tuning a couple of pics and he spotted what i was doing wrong. After that it was simple and easy.
