A frame has to be designed to accept a belt drive (needs a drive-side seatstay that comes apart) and disc brakes. Your frame apparently isn't designed for those components. That's why bike shops are turning you down.

I'll admit that I'm not great with spatial relationships...But the photos in post #14 make it appear that the frame, as-is, will not take a belt.
And I'm sticking with my response about the disc brake. You can't just add one to a frame that hasn't been designed for it.
