I'm doing mine right now, I would think a pro could get it done in under 10 hours.
It took me about 3 hours to tear it down, the new rings were a real pain in the ass to install, but if I had to do it again having already done it once, it wouldn't be so bad. My head will be here Thursday so I'll finish it up Thurs/Fri night, maybe into Saturday AM.
