And my answer is double whatever is the highest posted so far!
Seriously, tho, we haven't had to sub out like this for emergency work. I'd charge what we charge our clients plus a bit more for doing the other cleaner a favor. Flat emergency service call of $250 for during hours, and more depending on what time after hours. Bill by the hour after that for straight extraction. We aim for $250 per hour so at least that.
