you should be able to get a gallon of epoxy resin from
Epoxy : Epoxy Resins and Hardeners shipped well under $100
I've purchased almost $ 3000 worth of supplies from them in the last few months, and they haven't failed me yet.
But if it were me, I'd lay it up with vinyl ester
Polyester Resins
and woven roving or better I use 7725 for moulds, but
I do however believe you are underestimating you materials for a boat tail.
If you want to come on down, I have a chopper gun now :-)
