Try Lucksy31 on the boards here. He does vinyl decals for amour and whatnot here, otherwise check around for stores that do vinyl decals. I'd post the link to one I've bought from in the past but I lost all my links in a recent crash/format. Another option would be to check out tuner/ricer forums and find who they buy there decals from. They actually make film coatings that you can stretch over the vehicles panels and change the colour for far cheaper than painting, you can even get carbon fiber look that way and I think the film is rated for 5 years without damagaing your paint. Hope this helps for ideas, sorry I don't have any specific links for you.
