Danubhe, did you look around at local printers? Not Kinkos or Office Depot, I mean actual printer shops. They can do a single deck on up, and can quote you prices based on what paper you want & how you want it printed (digitally or the regular way).
The printer house Rota used required something like a 2,000 deck minimum, and Carta Mundi (they have an office in Tennessee) doesn't go below that either, but local printers are a lot more flexible. They'd be in the yellow pages. Pennsylvania HAS to have someplace that can help you out, you can do a lot of phone checking by asking if they have the capability of printing up a deck of cards on stiff cardstock - that gives them a good idea of what you want to do, you can fine tune the details if they say they can do the job for you. Many should be able to. It's gotten quite normal for businesses to have specialty card decks printed up with advertising on the card backs, so if the printers can do those, they can certainly do up a tarot deck or 20.
