"Value is in the eyes of the beholder". That's a Shakespeare/BIG CHEVY 3600 quote. The thing is, you have several answers and all are correct. Here is another proposition - if I were to want to do a frame off restore of a '52' 5 window and make it a street rod with V8 and the one you have would fit the bill, with not too much rust repair, I'd pay up to $3000,00 and thank you for the disassemble job. I would, however be looking closely at that dash work needed.
That should do it! You have estimates from 200.00 to 3,000.00, pick the one you like and run with it.
