Think that's bad? Try doing it yourself! I have a tractor to move most of the earth, but the last 2" of hand levelling a 24" (larger, actually, since my yard has a grade and I had to cut into that to level the pool and want to leave a walkway around the pool so I don't have to put up those ugly plastic fency thingies around the top). Got about 1/8 of it levelled this afternoon (was too hot to got steady) and it's really depressing to look at the rest and think "what the heck lies underneath those last 2 inches?" My pool will sit on part clay (easy digging) and part old soil with roots running through it (an utter bear to dig and level). You've got it easy, my friend - write a cheque and wait.
