I posted awhile back about selecting flooring for our farm office and apartment. At one point I'd considered acid stained concrete; however I like a more clean & polished look and am concerned about the appearance of stress cracks (there's already one). We have infloor heat.

I recently picked out flooring and my husband came across sticker shock. Shown below are my present choices. It averages $12/sq ft including materials & labor. Are my choices exorbitant? He says no way, just find a cheaper way. Suggestions?

Here are my present choices:

Main floor offices, conference room, break room & restrooms: Shaw brushstone 18x18 tile using Ditra. 4 areas of decorative inset.

Main areas of apartment: Adura Lock solid

Stairs: Adura plank

Bedroom: Shaw Stainmaster cut pile berber - nylon

Does anyone know the materials & labor cost of acid stained concrete? We're in the midwest/great plains area.
