Need Help For Boat Fuel Leak

My 1987 GW 204-C I think has a fuel tank leak and hoping to get it replaced by vacation time May 5th. I just found out about the leak.
The trouble is - I am having trouble finding anyone down in that area that can do it, that is not swamped with work. Does anyone know of someone that works on boats that could replace the fuel tank? It is a 65 gallon tank.
It is in a shop right now, but they are doubtful they can get to it anytime soon. Getting worried....need to fish
Thanks

Big job.....the guys I know did it themselves.....all but the fiber glassing.....saved I would guess around 20 grand
If the tank plan on replacing,
