I am trying to get an estimate on pouring a concrete basement for new home

I know it is very difficult to give an estimate for concrete basements without having all of the information. All I am looking for is a ballpark figure, so it is around 900 square foot basement with 8 foot walls so that would mean i would need 9 foot high concrete I think, the lot is free from rock for most part I was told also the home is a 2 storey 2700 square foot house with attached garage.

If there is something more I need to describe just let me know.
