I reckon your next step would be to figure if overland or barge/truck would be cheaper. Lynden Freight is in both AK/WA as well as Canada. Not sure where your freight lines go, but I know there's one from as far East as Houston TX and up the AlCan. Freight goes either to ANC or FAI at Tok once you cross the boundary. They also have marine services for barge/flatbed. Stuff that's barged is usually truck-ready coming onto the dock.

Out of Prince Rupert, would hit the Alaska Marine Highway (AMHS). Click on the sidebar schedule in the link above.

The reason I know about these guys is twofold; I used to ramp for Alaska Airlines here in FAI, and have used their freight forwarding out of Spokane to get larger vehicle parts over to Fife, WA to be barged up LTL. If it hits the trucks right, I get stuff in 7-10 days.
