Best way to do it is a bobcat - backhoes are for digging holes, I think all you need to do is remove half a foot on the high side and dump it on the low side to essentially and raise the other half the pool will sit on. As long as you drive over it many times with the bobcat, it will compact plenty to install the pool.
I built my pool on a raised pad done similar to above, and 3 years later, it hasn't moved at all.
