Or in your example, £250 a days work at £6 pr House is over 40 houses a day to clean, compared to 25 @ £10 a clean. We both get there, but one is working harder and longer than the other.
What I think is more important here is how much of that £250 you can keep in your pocket.
I'm the £6/£7/£8 x 30/40 house type of window cleaner, your obviously, the latter.
But I bet after expenses I have a lot more of it in my pocket than you 
If you ain't got an ex wife, than Im sure you do.
😂😂😂😂
Come on, Nate; you're in Donny.
You can get rid of an ex wife and still have change for a fortnight in Scarborough from 250 notes.
