Thanks for that Suds.
£40k is the starting point, when you add on Con Roof jobs, gutters etc the skies the limit. I only do £40k of window cleaning because I do other things too. If I wasn't doing other things then the £40k could be in excess of £50k.
Where people get confused is that they won't just be buying a data base (as per normal round buying) but a popular and proven business name. That counts for more believe me.
Think of it this way: You have lots of money. Do you buy some minor non heard of chemical companies or do you buy ICI with it's proven name?
