Car window advertising

Those of you with a stick-on window advertisement for your websites/company...can you recommend someone who does that work?

I want one or two for my own vehicles but don't know where to go.
Any local sign company should know how to do that with vinyl letters.. they are the ones that do that kind of work.

Signs by Tomorrow is a good starting place if you have one of those locally... we have one that has done all my decals in trade (pizzas for decals) here in Littleton. Normally, the setup I have with the reflective lettering and installation would probably go for about $200. That includes the front bumper, back bumper, and trunk lettering.
