Carlile has done well by us. Shop around for rates, but give them a shot. Shipping from AK to anywhere will be much less expensive than bringing something into AK.
We provide a crate and crate motorcycles for $300. We usually use the largest crate we can find to avoid too much work on the unit. Most times there is extra space for things to be strapped down, dry bags, etc.
How it works with us is we'll get you a quote from Carlile, you drop your bike off and the bike arrives at the destination a few weeks later. The actual boat ride is about 5 days or so, budget a few days on both sides for logistics, and you should be set.
We do it all the time, it's pretty straight forward.
Any questions, just give me a call!
