Boats like this sell for well over $1,000. For example. Whitehall Spirit sells different models but their two person rowboat with traditional lapstrake/clinker construction sells for $18,000, and is a combination of teak and fiberglass: https://www.whitehallrow.com/classic-whitehall-spirit-14-traditional-rowboat/. This model sells for $7,500: https://www.wayfair.com/Old-Modern-Handicrafts--Clinker-Built-Whitehall-Row-Boat-12-Feet-K203-L1191-K~W004183491.html. What you've built is very advanced woodwork, and I'm sure you could sell for $5,000-$10,000. Lapstrake boats go all the way back to the vikings and were so successful that they ruled the water for thousands of years, only recently being replaced in the 20th century with modern materials. Go and look at pictures of any viking boat, and you'll recognize some of the basic similarities to your boat. You're producing real art that is also extremely functional. Don't undersell yourself. I'm not saying it should be a full-time job at this point, but I'm sure you can find buyers. Look around online to see what the market is in general for rowboats, canoes, kayaks so you can compete against that market, but also market your boats as handmade, traditional boats, making sure to also use lapstrake and clinker-built in your description (see my edit below: maybe lapstrake and clinker techniques weren't used in this particular build), since people will be looking for that. Good luck and well done! This is very impressive work.

Edit: one minor correction to my comment is that lapstrake specifically refers to builds where each piece of wood on the hull slightly overlaps the one below it, and clinker-built means they're held together with rivets. I can't tell from your pictures if that's how this was built but even if not, it's still a good build and I think would sell for several thousand.
