Depends how much you want to spend and if you want tig or mig and chromoly or dom. There is a shop in lakewood that builds pro stock chassis and they can weld just about anything. They are mainly word of mouth however but i can talk to them if you want but you are going to pay more for a cage there than you would at most shops because of the quality, the shop is called Lazarus Race Cars. Other than that there are a few shops i know of that could do a cage if you had a bender and a mig welder i could do it. If you want it professionally done and notched then i know of a bunch of shops that could do it. Pfi does pretty good work up here in fort collins and have a bunch of cages to show you. I know most of those guys pretty well so if you want me to talk to them for you i can also. If you want some more names i can give you some more but those are the two i would recommend.
