Hello and welcome. You should be able to find more work than you can do in Houston. In addition to the companies jpgilham gave you, I recommend Bare. They have some national work and you should be able to pick up some shops from them in Houston. You might also consider Jancyn, ICCDS, and New Image. I'm northwest of Weatherford and sometimes shop as far south as the Waco area.
