Can you stack the wood and let it sit until it's dry and easier to handle? At 200 pounds each there aren't many, even on this board who are going to carry them around, but you might be able to roll the big ones into a line and stack the smaller stuff you can handle on top. You can let them dry and split them at your leisure at that point.
Those are big honking chunks of wood. If you don't hire someone and rent a splitter (which I recommend) I strongly suggest using what I grew up calling a "Monster Maul"
32911 - 12lbs Splitting Maul,30" Steel #Truper rather than the old fashioned blunt maul and wedges. They make a huge difference.
