Here you go....Precut auto tint. they also sell uncut rolls of whatever width (20" or 40"), length (1',5',10'20' or more) and percentage (5%,20%,35%, and lighter) of tint you want.
I`de go with their Solar Guard brand. I just tinted my car and will be doing the wifes minivan front windows. 35% is perfect as it`s not too dark and cuts the sun and heat coming in. 
Lumar is supposedly the best, but I couldn`t find it anywhere by the roll. There are other places out there that sell it the same way.
Good luck!
WOW!! Checked out the website, and talked to them--it's perfect. You can buy samples for a small fee in order to get a better idea of exactly what type and what percentage of tint you want before you buy a roll. Also, being able to order it by the foot is fantastic. Thanks so much again for the information!
