Try the shipping section in (Getting there in the planning section) and look for my experience Bris to Vancouver about this time last year. Most of the info will be relevant to you. Well worth it to ship just depends on how long you plan to be over there.
I have a more comprehensive detailed Excel spread sheet if you want. Just email me and I will forward you a copy.
I have lots of more useful info for a 9 week 18000km trip Rockies, Trans Canada & US if you want.
