How much for a complete Rehab

[Ebahi Ejerekhile]

Any contractors that can give me an estimate on the cost of a new build.  The house on the current property will need to be taken down.  Lot is about .25 acre.  There is no garage. 

I'd like to create a 3/3 or a 4/3 between 2,500 - 3000 sq. ft.  I'd like to add a 2-car garage and a flat top (instead of a roof) since the backyard will likely be small. Let me know if you need more information.  

The house is north of Atlanta, GA.  If you are a GC please PM if you need to look at the space to give a better quote.

Thanks
