I would say you need to take a least £1000 a week to make any sort of living,
That might be what YOU need to take a week, but not everyone has the same overheads. It is very subjective.
Chemicals are cheap as chips now.
The major running costs in this business are IMHO fuel both for vehicle and TM
and Advertising.
The more advertising the more business and hence the more fuel.
So these 3 things are irrevocably linked.
And should be the same with anyone in this business.
#What is different and purely subjective is the overhead aspect. You may live in a 10 bedroom mansion that is mortgaged up to the hilt, and run a fleet of high price cars and women, so naturally your overheads are going to be high.
I on the other hand live in a barn, with no mortgage, very low rent and no real outgoings, so my overheads are negligible.
You may need to earn £1000 a week to make any sort of a living.
I on the other hand only need to earn that in 3 months and still have a good standard of living.
So as said at the begining everything is subjective.
