It can vary depending on where you are located and the how difficult it is to dig in your area. I also depends a lot on if your excavator needs to haul off the dirt or can spread it on the property.

You should also shop around as prices may vary considerably and you don't necessarily get what you pay for. I would say in my area of northern Indiana $4000.00 and up. I had a guy quote me $20,000. Please!
