I should have been more specific . . . I stripped and installed the skins myself. Shipping the whole seat(s) would be exorbitantly expensive. As I recall, shipping to the US for the observer's seat was about $30 each way.
So I guess it really comes down to how much of the work you are prepared to do yourself. If you are prepared to tackle the install, (removing the skins isn't that hard), then you could use anyone. If you are needing someone to do the install then you're pretty much stuck with a local shop.
