Stamped and Colored Concrete
There are a number of 'factors' that come into play.
It depends on where you live, the 'demand' for such services, the terrain, stamp-style, color, and so on. If you want a ballpark estimate, take a few photos to a Contractor (instead of him 'wasting' his time for someone who's looking for an 'average' and not a job to be done) for a 'rough estimate/average'. Be polite and ask for a HIGH and a low number. And DON'T ask for anything in writing. You just want an average/estimate to think about.
My best to ya and hope this helps.
