If you are willing to go a little further afield, 3 years ago we had an entire aluminum bimini welded up by Isaiah in Port Orchard, WA. He works as a welding supervisor in Bremerton Naval Shipyard, but has a really nice shop set up at his home. He is experienced, knowledgeable, and easy to work with.
He is also also an avid boat and fisherman.
He did a lot of really quality modifications to his own boat that I saw.
I designed and cut out all the parts for our bimini (I have a CNC plasma cutter), and he did the forming and welding. Excellent work, and he made several significant suggestions that resulted in a better bimini than I had envisioned. His phone # is 702.332.1766
Tell him Scot recommended him. (no relation of affiliation, just a satisfied customer)
