i dont think anyone would give you a accurate quote now.
As your house is not even built X_X
But my personal experiences, it will cost you around 60-70 dollars per one, including the LED downlights and installation. (Not sure how good or bad the light they are installing for me tho.But again, i doubt your builder will install a super good /expensive one for you... )
