I can print the vinyl for you. It prints and ships in less than a week. What I use is 2.1 mil vinyl as the printed substrate, print on that, then laminate it with a 1.5 mil laminations.
Results are glossy and, with the right image choice, spectacular! I'll include some image choices in another post but go to istockphoto.com or shutterstock.com to find images.
A word to the wise, don't skimp on the image. Get the highest resolution one they have. If you buy one with too low resolution, it pixelates when blown up.
Oh! Most important, price is about $300 plus shipping for 4x8
