Butterman Tool in Rio Rancho NM should be able to help you. I've been to his shop and it is quite impressive. He's made a custom automotive piece for me where no one else could and as an added bonus, he was the machinist that Andy Payor of Rockport Technologies used to custom machine parts for the first Rockport turntable.
He doesn't have a website but here is the location/contact info:
Johnathan Butterman
504 Frontage Rd NE # A, Rio Rancho, NM 87124
(505) 891-2758
Cheers
