Frank is out of my price range. Not paying $1900 for a frame. I've found some local welders who are certified. Haven't contacted them yet to see if they can handle thin wall tubing. They'd certainly be able to do a better job than I could after taking some welding classes. If I hand file the miters myself, the price would probably still be well under $1000 even with the welding services. The major problem is there wouldn't be any jigs to ensure alignment.
