Gaza me ole mate
I can see where you are coming from but believe me when I say that the fundemental flaw in your plan is human nature.
I've been their, done it and worn the tee-shirt where this sort of thing is concerned. Sorry to tell you this but you will be very lucky to have a good experience doing it your way. I would be very happy to hear that you can prove me wrong though.
I have a sugggestion for you. Try it Williamx's way. That is just get a canvasser to bring you
GOOD leads in then you go and price the job up and use you so well publicised "charms" to close the deal and get the business. I honestly dont think you can say X for that window and Y for that one etc. What about access etc? it all needs to be taken into account. I still price stuff up too cheaply even now
( not often though)
Then pay the canvasser the value of the 1st clean. OK you say he/she would have earned £14.00 in that hour you did. Really honestly that wont happen all the time and for this type of work it isn't enough to motivate them to get out there much at all.
Oh well I've said enough on this. I am talking from experience here and get that gut dropping feeling about it.
Sorrry mate I hate to put a dampener on things for you
Go on... I hope you can prove me wrong
Cheers
Andrew
