Ring around, try Nuplex, Composite Supplies, and Adhesive Technologies first.
Give the scope of the project, get a 20 litre of resin, and about $40 of lightweight woven glass, and about the same in a medium weight CSM.
Use aluminum foil tape instead.
There's an arse load of stuff you'll need, budget round $500-1000.

Talk to your suppliers about resin, probably a VER (for chemical resistance) is what you want. 20 litres sounds a lot, but it's not really. VER is cheap, so it's good for building moulds from too.
Having said all that, you have no idea what you're in for... imho you'd be foolish to turn this offer down.
