if you only cleaned residential properties only mixed price and the average overall was £10 per property you could do 20 per day x £10 = £200 x 7 days = £1,400 x 52 weeks =£72,800 if you had 6 employees all doing the same then yearlly turnover would be £436,800.00 .So thearetically you could turnover 1,000,000 within 3 years but thats turnover before wages,van expeses,insurances,income tax, etc etc etc etc etc so theres you figures see you back here in 3 years
