Concrete contractor: need budget numbers for a basement

[IMaDad]

I am doing the first stages of a feasibility study for building a home.

I need to know average price per square foot for typical residential basements in the ATL area. I understand site conditions and specificiations vary. just average.

Now, I do have some specific design features that are not common for residential use that I would like to see budget numbers on, and eventually hire your company to do. Thanks
