Try these, they are the 2 largest fur auctions. They'll have 3-4 auctions annually and they'll take any amount small or large quantities. Contact them in person and they'll talk you through the whole process, but a word of warning, if your furs aren't prime and put up somewhat well, then you're wasting your time and money.
You don't need a license to sell furs, some might ask for you're hunting license number.
The Fur Harvesters Main office is in Renton, so I usually just drive my furs down there.
Good luck.
