I don't know anyone in Alaska, but what I would do is call some of these shops and ask them, as the beaver community is a small world, as I have found out.
On the canadian coast, I know of Viking and Sealand. In Seattle, it is Kenmore. And in Minneapolis, Wipaire is big. All those shops do rebuilds, and can give you recommendations I bet. there are several smaller places too of course.
I am a few months from being finished with the one I am doing, using one of the shops and they are doing excellent work. I had to do a lot of research on various stc's etc in case you have any questions I might be able to answer.
