What to do next, me thinks

Right heres what ive done and what ive done since, let me explain. when i bought my car it was a standard lwb tt i think, but had an aftermarket boost controller fitted. the boost controller had no instructions and i didnt and still dont know how it works, bassically i wound it up and done my oil seals in my tubs. Now over sometime i have taken out engine replace with newbuilt tubs with 360 degrease bearings and stagered step oil seals or something like that. also i now have a large enough k a n air filter that feeds more clean air into the engine than the channle tunnle needs, and one super large front mount intercooler.

The car runs sweet as a nut but it hasnt been further than a trip on a car transporter to my brothers garage so i could catch up with the wielding brake pipes and stuff ready for pre mot.

I am now thinking im wanting to put car back on transporter to somewere who can put a new cam belt on and set the car up so if once setup just turn the contoler on and of so i can play without killing it again, and im just glad one of the tubs were weak proberly saved me from killing engine.

IS THERE SUCH A PERSON TO DO THIS AND HOW MUCH?

may thanks, once done ill finish the car with new gloss black paint to match the new satin black wheels and once more a lwb uk tt back on the road . Thanks for your help.
