WOW?

An interesting read and some very DIFFERENT ideas on what is and isn't right?
My call is this.
I live in a medium size town with an estimated 29,000 houses.
Out of those 29,000 50% won't or can't afford a window cleaner.
Out of the remaining 14,500 probably 25% are the less desirable houses lets say.
Out of the 10,875 possible customers I think with my canvassing and company background of 15 years I would have a more than fair chance of getting 5% of these which would give me a customer base of 543 houses.
Now our minimum charge is £10 so lets say half are 1 x m and half are 2 x m that gives you an average monthly income of £4072
Now thats just my local area, we cover 3 COUNTIES so think about the possibility of customers?
My question is this, with so much work available out there, why:
1) deliberately undercut another window cleaner to clean someones house for less than what they were happy to pay previously?
2) Be prepared to work on a lower rate than you could have achieved had you got your own customers?
3) are you not prepared to knock on the next house until you find a house who hasn't got a window cleaner and is prepared to pay the going rate?
No one has any rights to any area and they are a fool if they think that. However, likewise, it is a very sad person who deliberatley takes work away from someone else when there is so much work out there.
Lets fight like cats and dogs when EVERY house in the country has a window cleaner, lets worry about that when it happens!
Guy's we should be working together and helping each other out?
