Too broad a question Trenton, it all depends on the industry. For example, an Architect would greatly benefit by having a site to showcase their work, while a plumber can probably get by without one.

The easiest way to pursuade someone that they need a web site is to show them their closest competitors sites! I also always tell people it can't hurt to at least have a simple page with their name, address and phone number on it in case people are specifically looking for them.
