£400 a day is achievable, but not everyday.
For one man, I’d hazard a guess that the average earnings for a days work is between £100-150 across the uk.
But then... If you look at the average wage of window cleaners in the uk, (by stats) most window cleaners should be skint
Having said that, even if guys are making £100 a day, that’s not a bad wage for what it is. When I look at what some people have to do for £25k a year, the hours they work, the stress etc. It should be appreciated that shiners can do 5 hours a day and pull in £25k a year fairly comfortably.
