I told him my max target price as mentioned above. Fiberglass units will knock some cost off, and perhaps that will be the most economic route for most people involved, and I'm fine with that. I really wanted a carbon version because I think it would look really nice with the color of my car, but once the mold is made then I can make one of my own desires. The guy was going to do some checking on current prices for materials and get back to me with a more solid price.
Time frame is a bit open still. He's not working anywhere currently, and isn't looking very hard. He's an enthusiast and is very interested in this project from that standpoint, and willing to do what he can to keep costs down as he realizes this is for people in small #'s who really love their old Audis.
Here's to hoping this all works out nicely for us
