I have been cleaning windows for many years off and on, mostly part time, been full time these past six years. This past winter I have been so fed up with the weather and everything I have been seriously thinking of starting up the dog walking again. Its a good business and people love their pets, they mostly don't care that much about their windows. I did a bit before and was impressed with the potential, espescially here in London. I am having thoughts again. its a good business, not least because most customers are every day regulars. Does anyone else do it?
