Lance, I think Sandpiper is the "go to" guy for an estimate. I would not attempt this repair either, BUT, You made the statement that you would not attempt any other job yourself.
May I suggest that the age of the boat you are looking at (or any other brand/size) is going to require many repairs. Some major perhaps, but most minor. If you proceed with any purchase,
you will either pay the equivalent of a much more expensive/newer boat if you need a pro to do these repairs.
I suggested the "BoatworksToday"' YouTube channel as a way to begin your education in boat repairs. There are dozens more covering everything from fiberglass repair to engine maintenance and rigging repair and electrical work. The list goes on to cover virtually every boat ownership topic. You will find that once you learn the skills needed, you will do a far better job of most repairs/refit that the yard "pro" you hire.
Hell, you might even enjoy the process. But that's just my opinion.
YMMV
