im not sure but you might be able to dig into the 'hillside' and get some of the dirt you will need. if your impact area is below the 8' rise you wont need to much dirt.
$100 an hour is kinda high. I know a man that did my work that's $75 hour.msredneck said:Been there done that....
Depending on the lay of your land...cut one out of the side of a hill...Of course depends on how much dirt you gotta move to get the whole thing fairly flat
Don't forget to make ya a shooting platform to shoot from...if ya wanna shoot rifles prone
Figure 2 days at $100 an hr
Main thing is you need a good dozer man...I know the best in Hinds Cty
