You've gotten a lot of good suggestions, depending on how much money you are willing to spend. The best way, as others have suggested, is a logging winch; but the expense is hard to justify for a low volume of wood.
Here's another, if you plan to process it into firewood; do it in place, then bring it out on a trailer. We handled a lot of wood this way when I was growing up; I've even brought my brother's winter's wood in using a trailer behind an ATV; or another time I simply stacked it next to a trail with a tarp over it; and every Sunday I would bring out the next week's worth using my snowmobile and tote sled.
