For liability issues, you'd have to do this yourself as there prob wouldn't be a shop that would touch that.
No one would notice if you put Llumar Air Blue 80 ceramic (or equivalent from 3M or others) on your front side windows, especially if you have a darker tint on the rear side and rear window.
For the windshield when parked, just use a folding Windshield Sun Shade with a highly reflective surface to the outside.
