I had a guy do one for me north of Olympia many years ago, the price was good and he did a great job. I can't remember his name but might be able to narrow his location if needed. Also had a guy do my sides and back for my Alumaweld, he is in La Conner, he did OK, and was a decent price w/o much of a wait.
You are probably looking at $1600-2000, I would guess.
I built a hard top for mine since noone seems willing to use waterproof zippers for the front entry hatch and those little flaps don't seem to work well when using the boat through the winter.
