You could use the same formula to argue how much do you 'earn' while sleeping or taking a dump
I think I will take this topic in the wrong argumentative direction but.....
How much an hour is the most misrepresented quotation used on here, moan about the price of something and you get some cleverclogs telling you "ask the £100/hr carpet cleaners"
On domestics We average £120/ hr which to me is how much I earn from pulling into the drive to pulling out. To me that's the most important figure, from this I can aim to create a situation that allows me to maximise the time I have to put me in people's homes earning that £120.
In an hour 2 of us can clean an average living room & HSL. I don't think £120 is an exorbitant amount of Money.
I only make money when parked in people's drives not when I'm driving so I need to work my diary to cut down on driving time and make my marketing bring in bigger, higher end work that is close to my home
