3d Printing at a Fab Lab or you local hackerspace- If you don't have your own 3d printer then a local Fab Lab or hackerspace may be able to do it for you. Fab Labs and hackerspaces are places that have invested in the machinery and you can take the designs to them. Generally they need .stl files to import into the software that runs the machines but this should be discussed with the Fab Lab or hackerspace. You then pay for the colume of material or time or a combination of the two for each of the parts or any other agreement in place. FabLabs:[3] Hackerspaces:[4]
