I find this is one of the best times to choose against the personal touch. Find all the sites that suck in your town and send them one proposal. You can even title the email "Does your website suck?" That will get their attention but leave open the option that you are not directly targetting them. It will get them to ask the question themselves without feeling as though you are singling them out. Point out some of the most common sucky features of poor web design as well as some examples of sites that sell. But before you send out any bulk email, read this thread [webmasterworld.com].
