Est. cost to replace deck

[Wireman]

Hello fellow Seacraft owners, I am asking for help in determining the cost to replace the deck and fuel tank 156 gal.of my 23' CC 1985 seacraft open.I know it will depend on whom I hire to do the work, however it would be nice to have a $ number going in so I get a fair estimate. I only have soft spots around the corners of the console right now, however I think i am better off replacing the whole deck and placing a new fuel tank in. Any help in your suggestions would be greatly appreciated. Thank you for your response and time...
