Is a lot easier than spending my own
For what its worth, on a 35 ft boat, IMHO, you cannot beat a convention fully battened main sail with lazy jacks and jiffy reefing. On a bigger boat (50ish), the pain/benefit ratio of in mast or boom furling balances towards these options. I've have owned both of these extremes.
So if I could spend your money, I'd buy a new mast, and fully battened main. If I could spend even more of your money the new mast would be carbon!!!!
That said, good luck with whatever you decide. If there is an experienced rigger in your neighborhood, with good references, I'd check with them as to what's possible along all the options you are looking at.
Seriously, most important is to get something that works that fits your budget and get out there. Good luck!
