I have moved very large rocks solo before, it's hard but not impossible. What you would need is as many 4' logs as you can find. The straighter the better. YOu also need a longer very strong pole. You start by digging out one side around the block and making a path of poles on the ground. You then dig out under the block and getting poles under it. I helps to have smaller rocks to use as fulcrums and to brace it up.

Once the block is on poles you slowly roll it, stopping it every few feet to move the l=poles you already rolled over to the front of the line.

It might take weeks but fuck it, $31 million bucks, i can survive in the woods for long enough to roll that shit out.
