hello mike
at the end of the day, if the client gets the info they need, and then ring you for a quote then you would guage that the site is working.
i have a friend, not in clenaing, but he always asks where a client got his name, and the two answers are, from a friend who has used you before, or from the web.
therefore i take the view that as long as the site communicates the right message and gets the visitor to action their visit.
regards
martin
