I just calculated out 31000 for all you mentioned not including the cost of the hull. I did not include things like sand paper, paint rollers, hand tools, you will certinly end up buying a few power tools cause something will take a crap and you have to buy a new one or you will want some new tools. I also figured in 1000 for good quality deck hardware. You will also need to figure in electronics, and things like fittings/thru hulls......the list goes on and on and on and on.
All in all I think you can do it for 35K if you are real careful how you spend your money however you may end up spending a little more then that.
If you are the type that wants to do everything right and make it look good then you will be hard pressed to get it done in a year working just weekends. You will probably have to work many week nights as well and then if you are extremly fast it will probably take you closer to a year and a half. IMHO
