As far as I know, they are happy to sell to anyone at the prices listed, and I'm not sure what air mail prices are right now, to be honest.

To my knowledge, there really isn't any such thing as a "licensed kiltmaker", in the way that there are licensed professional geologists, for example. You don't have to have a license to practice kiltmaking, although, if you go to the Keith Kilt School, you can earn their certification, if you think that such certification is valuable. There's also a Kiltmakers Guild in Scotland, but, again, you don't have to be a member to practice kiltmaking. And, although it started out as being open only to Keith School graduates, I'm virtually certain that it's now open to others.

That's my understanding, anyway. I hope if I'm wrong about any of this that someone will post a correct version!
