Dude, really. The motor is the easy part. The hull is a ROYAL BIAATCH!!! Especially if it's in two pieces. Fiberglass will cost you $$$$$ in material alone. Doing it right will strain your patience. The single largest labor intensive part of a boat build is by far wood and fiberglass. My Enforcer motor is on the stand with an empty block. It will take one afternoon to put it together. I've been working on the hull for four months and still have more to do.

Maybe some others know of some other places. I love their resin. Gives you over 30 minutes of work time. Be sure to use a roller or it will delaminate in no time at all.
You really need to get the bottom on a jig so it's squared up, then get the two halves back together.
