Dear Mrs Custy
Sadly, due to winning a major contract in (name a town twenty miles away) I have had to consolidate my window cleaning round. Rather than me struggle to keep up with all the work that is flooding in I have carefully sought out somebody who will give you the service and regularity that you are used to.
Therefore I am introducing you to Shinum Heapfast Window Cleaners who have been in(name custy's area) for several years and who are looking to expand their family business and who in my opinion will provide you with a first class service.
Please be assured of my best attention at all times,
WW
