It's not really that difficult. Your guide or outfitter usually gets the tags for you. The other thing is the meat. You can save some pretty good money by driving up and bringing your meat back yourself. If you have to fly it out it's going to cost alot more. I did a hunt in Canada this year and my first step was to figure out my budget. Then I figured out when I wanted to go and made sure I had time off. Then I figured out what animal I was going after. Moose have a rut and Caribou have a migration and so forth, so make sure you plan your hunt and get time during the peak period for that animal. Myself.. I then figured out which area's I could drive to and wanted to hunt. Then the search was on for an outfitter. You should get a bunch and whittle them down as per your needs.(Fully guided,Fly in, Drop camp). The internet is a great source for that info. I am doing Alaska this year and started out with about 25 outfitters and have narrowed them down to about 3. Make sure you get referances, as well as ALL that is included and what is NOT included. I like to email or talk with the outfitter to kind of get a feel for the guy and his operation. The next thing is to book the hunt. It will require a deposit and some will let you make monthly payments on the balance. This has been my experiance so far.
Any questions feel free to shoot an email. I could give you a list of outfitters and their email address's that I checked out,but it looks like you are on the other side of the country and won't be hunting Western Canada where I hunted.
