Tim was probably right, that you can't modify the existing frame for what you need. Mr. DumpsterDiver was probably pulling a fast one telling you he could do it for you.
Now that you are getting free of the "wrong" frame, maybe ask Chris if Mondonico can create a frame, the "right" frame, just for you?
Not modify and paint an existing pre-made frame, but make an entirely new one to meet YOUR measurements and YOUR requirements?
(Chris and Mondonico did it for Trek, I bet they could do it for you)
