Speedway,
Can't help you with Colorado, however you may want to get out the yellow pages. It is getting hard to find good tube benders. When I did my Shell sign I took a picture and started hiting the sign shops that advertised neon work. A couple of the shops were nice and said the best tube bender in the county was Al and I should go see him. I took an extension class in neon at UCSD, and I learned they earn every penny they get for good neon bending. The 50 bucks for each side of my Shell sign was worth it.
Good luck,
Ed
