ok I have a question, I'm going into the business with a friend who use to do window cleaning years ago. and he talking about doing average 50-60 houses per day each, 2 of us working together, as i haven't done this before i can see me being a little slower then him at first, but i wonder what the average amount an experienced window cleaner would do per day, and how long per day it would take them, as looking for rounds that are big enough to pay both of us a wage but is also manageable while giving a good service.
advice please
