I'm from Dallas and there are plenty of places that will do work like that, Houston too.
I think your frustration is based less in the machining capabilities of the great state of Texas, and more in your lack of networking and research abilities, compounded by being accustomed to the convenience of your previous residence.
Rant riposte over!!
True! I picked up a 71 duster when I first moved here 2 yrs ago. Yes we are 1 1/2 from actual city of Houston. We spnt half a day going everywhere that sold steel. Finally fond a shop that sold welding supplies, and steel. I get them to order a sheet of 18 ga. I go back next week and they have 16 ga and tell me they could not get 18 ga.!! There are more welders, and companies that deal in welding, supplies, steel right here than bout anywhere in thee USA. Back in Mo going to a steel shop and getting what I wanted that day was no problem. ha..... I admit IF I drove into Houston and all of its traffic, and spent all day, I could find whatever! Assuming I wasn't killed while there! ha again!
Thing is when you live further from a big city, the local businsses do what it takes to run their business and support the needs of the population. If you live 1 1/2 hr out of a BIG city, (like here), where half the rural population drives that 1 111/2 hr to work in that city( because that is where their big check comes from) , it is a different world.
I had 3 shops that did custom exhaust with 15 mi of me back "there". Here I have fond them all, 1 25 mi away and the other 60. The pop. here is this county is at least equal to back home, and pop when the nearest shop, the pop there is 20 times back home. I just find this interesting.
I am sure as time goes on, I will find more businesses to provide services I was used to having. I didn't mean to ***** so hard, and imply that Tx is lacking in any manner!!!!!!!
