In general how much does it cost for labor for installing tile $ / sq ft? how about for carpet?
In general means where you live. The only way to have a close guess is to call 3 different installers in your area.
Around here, 3 tiling contractors are about 3 miles away from each other.
You get what you pay for, good luck.
