Local universities or schools that have this equipment and skills in house? Or just a local prototyping business, they do exist and are more common than one would think.
I don't know where you are located but I know a few around me if you are interested. And if you really have a hard time I may be able to help you personally as I can CAD, CAM, CNC mill, turn and have stuff 3D printed by a good friend.
Good luck with your search
