If I go back to when I first started window cleaning I would have been very happy to get another customer and would have probably taken me 30 mins first clean (10-15 mins regular clean) and I would have charge £5.
Few months later I would have probably charge £7.50 double £15 first clean.
Several months on, window cleaning minimum price would have been £10 £20 first clean and so on.

To change the area of discussion, slightly:
I'm curious as to how you have dealt with your earliest customers whom you were originally charging £5, and your later customers whom you were charging £7.50.
When you began charging £10 (or more) for similar properties, did you increase the prices for your earlier customers to £10 also (take it or leave it) - or did you raise them a lesser amount and keep them on, out of loyalty - or did you just 'drop' them without any explanation.
There has been lots of advice given by other members regarding this 'problem' of 'what to do with underpaid jobs' - I'd like to hear your approach.
Are you a 'nice guy' or a single-minded, hard headed business man?

Whatever your answer, this will be my last posting on this 'thread'
