Online source for 4x4' vinyl wrap panel for trailer

[AZKayaker]

The previous owner of my CT has WWII planes on the sides and back. For some reason, he chose to stick the right side wrap, this Corsair, on masonite then glued the masonite to the trailer. The masonite in now mush and I pulled it off today. Scrapping the glue off now. I want to do another custom 48 x 48" panel to replace this one.

Anybody know of a good online source for vinyl wrap panels? Or a bad one to avoid?

I want to use my image and I'll install myself. Most wrap places here don't want to be bothered with a small job. Thanks.
