I was wondering if I could use mulch to level the ground for my above ground pool.
I was told not to use sand, and I have a hard time digging.

The mulch will decompose, leading to bad odors around the pool, or animals like mice could dig in and chew on your liner. You could use gravel, with sand or dirt spread over it to smooth it out.

I have a pool that's up but my poles are sinking on one side I need someone to come out and level the ground for me. How do I go about finding someone to do this

Alien, start another post on your own please. Wildandblue, absolutely not. You must remove sod and level the ground, then you can use some sand to make it perfectly level but not so much sand that you are using it to grade the site.
