I've finally got some prints available for sale through DeviantArt Prints. I've never used them personally, so I don't have first hand knowledge of the quality, but I've heard good things from friends.
I'm putting the Steampunk Star Wars series up for now. I've seen a fair bit of Star Wars fan art for sale, so I don't think selling these will be a problem.
Purchase Prints Here
Although some pieces are available at larger sizes, the best quality prints will probably be around the 10-12 inches or lower size.
If there's a piece of mine you'd like to purchase a print of and it's not in the store, let me know!
UPDATE: New Prints available!
