Skiddable structures are great, you can drag 'em just about anywhere. Now you got it there, you need to level it. Rocks to the rescue! Build a level "foundation" under your skiddable structure, to both level it and slow rotting of the skids.

This BB takes a while if you don't have a skiddable structure! So first I built a skiddable "farm stand" in the driveway. Then we wheeled it out by the mailbox and leveled it.
It's definitely sturdy enough to skid, I just put wheels under it so that we could roll it with people power instead of hooking up the garden tractor. And so I wouldn't mark up the driveway or yard. We also don't have rocks around our place. In digging about 80 post holes I've accumulated about a 5 gallon bucket of gravel and two rocks the size of a basketball. So I dug out the spare/repurposed/used blocks and bricks we keep for jobs like this and put them to use.
