Send me a PM - I am a machinist in a tool and die shop up near I-10 and West Beltway 8.
Depending on what you need I can probably fix you up myself, worst case I can certainly help you find a shop.
We have your basic machine shop tools as well as a CNC lathe that can turn 38" diameters and a CNC machining center that can cut 60"x32"x30" work. We have very nice CAD/CAM software so most custom jobs are no problem at all.
