Have you looked around on line? I'm not certain who is still in business and who isn't these days. I've heard glowing things about a mistress in North Carolina that actually does welding and has her own shop. If memory serves, she made a lot of equipment for Domina Snow's studio. I will get more information for you.
My friend and fellow poster, Tristin, knows a femdom lifestyler that had really nice welded dungeon pieces done. That is in the Houston area. I don't know what areas are you are looking to stay but will put out feelers with the people I know.
