Try the "Green Sheet" or "Thrify Nickel", etc, and check out all the ads for
automobile window tinting. Many of these places will also do homes and
offices, it's the same type of film (which works well, by the way).
OTOH, even my 80 year old mom has installed this stuff on her own. It can't
get any easier than putting the film on a flat surface (unlike curvy windows
in cars). You'll save a lot of dough doing it yourself.
