I'd use Solar-Tex, they did my car and are very professional.  I chose them cuz they're not just some "auto accessories" place, they do exclusively window tint for buildings cars, boats, everything.  My car was listed as a "difficult fitment" and cost me $170 total, guaranteed for life against installation problems and fading.

They're in the worthingtonish area iirc.
