The problem with our line of work is that we are not buying contracts.
Quite a few people like their window cleaner and that is why they keep him, especially the older customers.
That is why buying for 3x and more can be risky. But that is just my opinion!
A night on the canvassing can pull in about £50 of regular work on average I would say. So that is like earning £150 - £250 for a few hours work!
