Hi Wayne. I looked into getting a plastic form to be sewn into my messenger bag, but the cost was really prohibitive at this stage of my venture. I believe it was because the mold for hot injection molding wasn't very cheap, especially for 100-500 units.
Sorry about leaving you waiting in reference to your manufacturing. Thanks for the offer, I am actually not currently manufacturing anything that is related to your companies specialties. I will keep you in mind for the future though.
