Google 'canoe manufacturers' and go from there.
There are a few canoe and kayak magazines that will tell you about C & K shows, like boat shows but just C & K's. You can get all kinds of info there on the competition prices, features and quality of build and finish.
What's it weigh? It should be around 70# for one like that. For the length, it should be under 60#, but yours is extra wide and not really a performance canoe.
A few observations. You don't want the gunnel fasteners on the outside, especially sticking out like that as it will put deep scratches in other craft you sidle up to.
The seat supports look structurally weak, I guess you'll find out if they are up to the task.
Looking at the center photo...#1 The stem is pretty fat which is usually associated with the tupperware polyethylene canoes, as they can't make them thin as a consequence of being rotomolded polyethylene. Laminated are usually a lot thinner, 3/8" or so. #2 Compared to the gunnels, the stem tilts one way while the top of the transom tilts the other way. Maybe it's an illusion.
I assume it's polyester resin, with the mat and all. Polyester or epoxy is the same as far as UV resistance, they don't have much. The bare resin over the balsa stiffeners will eventually break down and cause problems.
If the inside is gel coated, you might consider substituting latex porch and floor enamel which will save at least 5 # in the final weight.
I'm not even sure you need 'rib' stiffeners, especially that big. The keel will probably stop any possible oil canning, and the mat will stiffen the laminate, although it doesn't add much strength. The one's I built had foam ribs, spaced about like you have yours, but they were only 3/4" high by 1" wide with a 10 oz cloth tape over them. There was no keel and they only covered the 'flat' of the bottom and stopped short at the turn of the 'chines' because the curvature there is plenty strong by itself.
It looks nice and nautical. I don't think I'd want to paddle it very far, but it ought to be fairly stable. It looks to be pretty fair on the outside, but it's hard to tell if the reflections on the bow are of a wavy line out of the picture or they take a straight line and make it wavy.
If you plan on selling them at retail price is one thing, if you plan on selling to retailers, knock 1/3 to 1/2 off the retail price. What you can do is haul that one around to various retailers and ask them what they think it's worth and then go from there. Most regular boat dealers probably won't have a clue and will be leery of buying an unknown product from an unknown source, but most would do it on commission.
As Par said, competition is very cutthroat, but the $7,000 price is their all wood classic canoe. It's not really comparable. What is vaguely comparable is their Rogue River 154SS at $800.

(except for the built in hog you can see in the side view. I can't believe they can sell **** like that.)
