This is probably the easiest if most expensive way to go. I'd suggest getting in touch with machinists/airsmiths here on mcb, as others have also suggested.
Regarding getting in touch with the latter, give them some time. They'll get to you when they can, as they're generally busy folks who paintball work is a hobby as opposed to full time or primary career - plus in many cases they have families, little kids and other such domestic stuff going on to keep them busy on that front. Anyways, the only point is to be patient.
