How many man hours and $ in rebuild?

[wes5.7]

I'm thinking about eventually getting a 20' seacraft. I'm leaning toward a CC. How many hours and how much money do you guys have in your rebuilds? I'm new to fiberglass repair so not shure I want to take the plunge. I'd just replace the transom, floor etc. not change the layout.
I'm coming from v bottom aluminums where you can redo the floor and transom in very little time and money if motivated. The ride is a bit rough in the bay chop though.
