I have an oval 15 x 30 above ground pool. It is custom in that it goes from 4 feet to 7 feet deep. I would like to remove it, fill the whole and make the back yard bigger and ready for the house to go up for sale. Can I do the removal on my own? What am I looking at to hire someone $$ wise? Has anyone done this before? I know the hole needs to be filled/packed/filled to make it sound and ready for sodding... Handy chic needs some advice please :)
