Lovely repairs you've made there. I wish I were as skilled at woodworking.
For the skins you are probably looking at near £1000 / €1000 (I know these aren't quite at parity, but this is a rough estimate) for a new skin, give or take a couple of hundred. Wayland should be among the cheaper options, but there are people on this forum who have had bad experiences with them. I possess a second-hand Wayland harpoon kayak, which has served me well; in my opinion the skin is better than the frame. The metalwork catches in particular are not very high quality (perhaps they've improved them since the 2000s). But it goes together and I've paddled it in some challenging conditions. I also have a Wayland skin on an old second-hand Aerius II, and again, I think it has been good value. (But I bought it with the second hand Aerius, so again, I didn't pay the full price, and didn't have to deal with their customer service at all.) There is a guy in the UK, Simon Bolze, who imports the Waylands, which may or may not be an easier option than dealing direct with the Polish factory.
http://www.waylandkayaks.co.uk/Victor's link above looks like an interesting option.
And there is Marcus Heise in Germany. He is the expensive option, but will do a fantastic job by all accounts. Have a search of this forum for some very satisfied customers.

I found gluing a pvc skin for my Tyne very satisfying—though there are inevitable imperfections that I'm aware of. Not as authentic as getting a hypalon and canvas hull, and if one can afford it, Marcus Heise is probably the best way to go.
Long-haul are highly praised on this forum, but being in the States, I would expect them to be prohibitively expensive when you factor in customs, vat and import charges.
