We are doing this kind of stuff already with adobe illustrator. I alway sassumed that sign shops had good art people because the two I've worked for did. But I see some drawings from other sign companies in the area and I want to laugh. The sign companies that have the crappy drawings are the bottom feeders though. Cut everybodys prices and spit out a bunch of junk. Back on subject though, I think the sign placed on a pic of the customers building or lot is a good selling point. Really helps them to visualize it and keeps the guessing out of how it will look finished.
