Small batch PC board manufacturers

A tip for you, check out the price for 10 off as it is usually the same price for 5 off pcb's. All suppliers I think have a minimum order of 5. That way you can sell a few to help recoup the costs. Postage costs are variable, but you can select what method you want.

PCBWay are very good and cheap as well - Nelson Pass uses them for his boards, but the Pass Labs commercial pcb's are still done locally in the US.
