OK most of the info has been right on, but if you and a friend drive up, it should not be that long, expensive yes gas in Canada is outrageous ,here it's over3.40 now.I have driven from the east coast by myself in less than a week, once from Billings in two and a half days,and with a friend we made Seattle from here in 2 days.
For someone like you, looking to DIY as much as possible ,you might look into applying for some of the draw hunts near the road system, if your lucky enough to draw you could have a good hunt, without the hunting pressure that goes along with hunting near the road, but be prepared ,a large bull moose is a formidable packing job if you are very far from transportation.
One more note swapping hunts can lead to problems here, unless the person your dealing with is a guide here, no one that isn't a guide can accept anything for services, and a swapped hunt would cross that line, as I understand it.
