i looked around at this as well and when i found out most shops are charging 2500+ most of them higher,
i lost the idea along with my wallet!!!.
It costs like 400 or so for the materials alone unless you want cheap vinyl. I may buy some cheap stuff and give it a shot my self, there are a few people that have done this.
But if you wanna spend the dough, i would suggest Wrapit-boston in waltham, or Design Flow Graphics in salem ma. oh and make sure you figure out what vinyl there going to use, the last thing you want is to drop 2k and have your black vinyl turn grey. hope this helps good luck
