I'm a carpet cleaner wannabe at the moment but i'll try to help you anyway. How many of these rooms could you get through in a 7 or 8 hr day? How much money would you like to take each day including labour & cleaning expenses? Say half an hour each room (14 in a day) so it would take about 14 days to do 200 rooms. What do you reckon, a quote of £3000 - (just over £200 per day?) experienced cleaners, correct me if i am wrong.
