you might want to check out this site called RedBubble. It is something like SmugMug in that it sells prints of different sizes, printed on canvas, or laminated, greeting cards, and t-shirts. The difference from SmugMug is that you do not have tp pay to have your photos hosted. There is a base price for each print which is what RedBubble makes, you get the markup, what ever you choose that to be. I'm not saying it is a good site, may not be, but if your interested in trying to sell some prints of your work, might give it a shot, after all it costs nothing, so you have nothing to lose. By the way, I'm not connected with RedBubble in any way, except I do upload my photos there. But take a look at the site, maybe something you want to try.
