While the 1" threaded standards may be deprecated in new production, there are still millions of bikes on the road using them, so I'm surprised that there are any shops that are unfamiliar with the standards.
I'm also surprised that you cant find a shop capable of milling the frame and fork to ISO standards, which would eliminate your problems finding a headset now and in the future.
