I have no idea if this place would be helpful or not, but I figure it couldn't hurt to put it out there. The place is called ProtoCam and all they do is protyping using these very expensive laser machines that make molds out of resins. They claim to be the largest protyping business on the east coast and they can do almost anything. I went on a tour of place last summer. They are located about 20 minutes away from the Bethlehem/Allentown area. Here is there website: ProtoCam
