I've done my own, and so has Stilov. I don't really know of any place that I would recommend other than
Modular Madness West. I've been going through them for dyno time, and they have a top notch shop with very good/qualified people. Ask for Heath, and tell him Daymon with the Turbo Contour sent you.
You might want to do some research in the 3L forum to get a game plan down before you shop around. There are many options out there, so once you know exactly what you want, what needs to be done... you'll be able to get an accurate quote from a shop.
