Unless things have changed, you can import the wolf yourself once you have the cites permit and save yourself a lot of money. It will require a trip back to get it, but might not be that big a deal for someone close to the border. I'm sure you could arrange with a local taxidermist to store at a minimal charge.
I ended up leaving two skulls and a marginal hide when I found out how much it was going to be to have them expedited across the border. In hindsight I should have had the outfitter just hang on to the skulls until I came back the next year and brought them back myself.
