Give Keith a shout at Chuforia Graffix. I'm sure there are others, but since I'm the first to respond, you get my favorite supplier. I know him from the Lotus world and he will take care of your needs, is great to communicate with, and accepts Paypal! All you have to do is give him your required dimensions and choose from his wide range of colors. He can supply regular adhesive vinyl as well as static vinyl depending on application.
