on all of my other cars (i have not, and probably will not tint my MKV) i have taken them to Silicon Valley Auto Glass. they are in south san jose on blossom hill road at snell ave. i do not have their number, but a simply google search should land you more info if you are interested.
they do pretty good work. on my 1.8T golf (4 door) they did a pretty bad job on on the hatch glass. i took it back, no questions asked, and they fixed it beautifully.
