i joined the george user group and asked this question. I was thinking or landscape gardeners and grass cutters because I see three times as many of them as I do window cleaners and they have address details, frequencies, and prices charged the same as we do.I said that paul (george systems) could call it Percy (Percy thrower being the iconic gardener as in George Formby). I also suggested that we could split the money, but he hasn't got back to me.
