Richy I do enjoy your posts and so do many others by the look of it
why don't you employ a good window cleaner some one who will go out clean,
deal with custy's and let you sit in your office organising and taking care of
the paper work.
On that turnover I would be looking for one good man and two average joe's
to take care of the manual side of the business leaving you to do as you please
I mean build your business.
Whatever you do good luck.
