Here's a link to one of my favorite websites: Well written, easy to navigate and easy to use. Decidedly unglamourous, but it follows the basic principles of good web design for small businesses. The phone number is the most prominent feature on every page and the answers to basic questions (what are the services, how do I pay, etc.) are in a lefthand nav bar and thus always just one click away from the page you are on. Plus, there's a sense of humor throughout--check out the FAQ.
