Who in Houston Texas area can rebuild drivers seat for better lumbar support? on 2007 Cadillac DTS

I have lower back that requires a back support. Since this is a vehicle that I plan on keeping quite a while is there someone or business in Houston, Texas area that can re-build the lower back area of the drivers seat for added support & comfort as well as keeping original appearance of the interior.
