Well if you want to build a boat tail and feel like coming out here I'll be happy to take a few days off and help you build it
Fiberglas is not have to be very expensive when you're at the hardware store you should find a 1 gallon container of the resin with hardener for about 35 bucks. 8 sf of cloth is about 6$. If you need a lot of fiberglass cloth you can order it online or look for boat supply storehouse. they often carry it in a 36 inch wide roll and you can buy it by the yard. That's what I should've done with my boat tail. But I did not know about it as I was just getting started.
