Ok ... assuming you're not on Teeside and everyone is losing their jobs at the local steel works this is a suggestion for you. Amend bits in red to suit
.
Dear
Mrs Newcusty,
As you know
Raggitt and Runn windie cleaning have given up their round in your area and I am available to take over the work. Speaking to
Roger (Raggitt) I understand his rates have not gone up since
World War One and I feel I must address this issue to make the round viable.
Therefore the new rate for your property as of March 1st 2010 will be
£XXX so as to reflect what I am sure you will agree is a fair and sensible price.
I am also offering the opportunity to change from fortnightly (luddite oop North if'twer good enuff fer my granddad then it's good enuff for me
) to four weekly at an extra
£XXX if you prefer.
When I call perhaps you can let me know whether you want fortnightly or monthly cleaning from now on.
Yours most sincerely, I remain
Your most humble servant,
Wezzy 32
