Hi, I use a similiar cash collection print.
I also use the back as an advertisement
chance, letting my customers know that I
also do Soffits/Facias, Gutters and when the weather
gets better Jet Cleaning (Pavements etc).
I have got quite a few added jobs this way.
Perhaps worth thinking of; you have the customers,
but do they know that you also do more than just
clean the windows ?.
