$300-$400 range BUT we are mainly commercial and that includes floor waxing, tile/grout and carpet.
On residential side we push tile/grout hard also
It can be a deceiving number especially for us, We had 2 $5k carpet jobs this month for example that will pull the "average" way too high.
Overall i prefer bigger jobs regardless of what service or residential/commercial, the bottom line is i am a completely incompetent administrator so the company is built to keep the daily phone calls/jobs to a minimum.
