Set up a "Generic", dentist website for your town;

"SalemDentists.com"...."PortlandDentists.com"...et c (The big city domains like this are probably taken but, I've found the smaller towns aren't)

Provide LINKS to each participating dentist's website. Websites that YOU have set up and...provided each of them with a Link from your Main Site.

Again...you send postcards to NewComers alerting them to your "Generic" site and charge participating dentists a Flat Monthly Fee of $150.

And...why not expand this "Generic Town Site" to include many other business and professional websites...all with a Link to their site that you've set up for them.

Call it..."WelcomeToSalem.com"...."WelcomeToMarshall.co m"...

Charge a setup fee and monthly.
