I did mine several years back and let me tell you it is something I'll NEVER do again. It was quite the project.
If I remember correctly the fiberglass cloth and resin came from U.S. Composites, marine plywood from a local place around columbus - I'll have to look it up, lots and lots of brushes and rollers for fiberglass from various paint supply stores.
I think in all I spent about $1400 on everything and no idea how many hours. I can probably write up some lessons learned/suggestions when I have some time or if ya wanna chat.
