Hey NlSS4N,
You might want to try Kinko's if you have one close by. I'm pretty sure they can do prints of just about anything, and then you could sell back for whatever price you want. I go in there to get resume's and whatnot printed off, and I've seen big printers that could be used for poster sized prints and such. They also have different styles of paper you could print on and everything. I'm pretty sure they don't do canvas printing though, so if you're wanting to do that you'll have to look elsewhere.
By the way, you really need to do a complimentary drawing of Guy to go along with Thomas from Daft Punk so you can sell them as a set XD
