It sounds like what you're describing is something like a cross between a pipe dream and what already exists. Wordpress already exists and there are many folks, and many or most without CS degrees, who will happily develop and administer a site for you. The pipe dream comes in when you expect those sites to generate sales and provide immediate value. If every dentist in my community uses your magical Wordpress site, will sales and value magically increase for all of them?
