I'm in Australia and I found these guys on the interwebby thinggamyjig and I ordered 1 custom made jersey. It was cheaper (including shipping) than buying a standard brand name, off the shelf, simple jersey (eg Pearl Izumi Classic).

In their FAQ section, it states that there is no minimum. You can always ask them if there can be a price reduction as you are from a club and it is more than likely they will get additional orders from time to time.
