I used to work for a sign supply company that sold vinyl and such to major chains.... you might try asking like "FastSigns" or whatever your local chain is if they'll do it for you. Some sign places are notorious for sponsorship opportunities and will cut you a helluva deal. Only down side to that is the chance you might have to have a vendors sticker in your window for a while.

 

Where are you located? I know of a guy who takes his time and does good work. Just did a 997 GT3 and an ISF for us.

 

if you are near jacksonville, fl. i know a couple people that do it
