But I've seen your skills, you should be fine.
Guy I'm looking at for my first 3D is Joe Morgan from Ray's Kits and Decals - he is a Pontiac freak of the first order, and had a G8 GXP on the table at DAAM that looked like it would go together very well.
He was working with the designer to sort some fitment issues, should be resolved one of these days.
I'm sure the others here would have some recommendations - have seen some from Too Many Projects that look pretty nice.
