Look to the DIY audio kit vendors such as diysoundgroup.com etc. These folks have experience shipping to off the beaten path places and perhaps getting your items disassembled and building (like speaker cabinets) what can't be shipped efficiently, or reliably, on site instead.
If I lived in a remote area that revolved around snow, I would have to have projects to fend off cabin fever. A whole audio system might cover one season of it if I was lucky. The other consideration being, that when living on skimpier parts of the grid, there is nothing much more valuable than self sufficiency, which is part of the reason one would want to live in such places in the first place, I would think.
