Ha Ha. More money than time. We'll take care of that for you...
If your boat is like mine you'll find the cabin walls made of 2"x2" handmade squares of scrap wood sandwiched between fiberglass sides. Elsewhere you'll find almost a complete wooden boat complete with knees, ribs and all the things wooden boats have inside tabbed to your fiberglass boat. Most will be good wood. The bad or rotted wood can be broken off and used as a pattern over good exterior grade plywood and re-tabbed to the hull. Anyone can make 2" x 2" squares of plywood. Epoxy is best used to attach things to cured (probably) polyester fiberglass.
The epoxy is expensive for what it is but the wood is cheap. This is mostly a time intensive project. You have to decide if time is money.
When you get to the finish wood work you can decide on teak or painted interior. But whatever you do start with full sized cardboard mock ups. Nothing on a boat is straight, level or plumb and certainly not the same as the other side. Cardboard is cheap - teak paneling ain't.
You have a great winter project in front of you. Best of luck.
