I don't know if the saving the world bit would work (as noble as it sounds), but yes, you can get some high-res images uploaded to CafePress and such and let people order. You can have a storefront with hundreds of items immediately available with the logo. CafePress is generous with returns and exchanges, but the prices are a tad high (though normal compared to other print-on-demand items). I ordered two coffee mugs and two shirts from them, and ONE of the shirts designs didn't work out well; washed off after two washes, so I complained; they sent the entire order over again, mugs included. Good service there. (The quality of the mugs is great; lasted 5 years and rolling, still look new, both on steel and ceramic... I had them made to promote some books I wrote and some Todd Beamer designs since I think he's one of the greatest American heroes of our time).
