I teach at FSU and have free access to a vinyl plotter. I do all the vinyl for the accademic museum so yeah, i've got some experience. laying it on cars is 100% easier than drywall, i'll say that! I'm not sure what they'd charge at a shop, our plotter uses a program called MacSign to read an adobe illustrator file. I know other folks will use Corel for vector graphics. I can absolutely attach the file to an email. I can export it in a bunch of formats. just shoot me a message and we can exchange emails if you're interested.
