Colorado plumbing contractor Tim O’Connor has developed a Web site to help consumers locate plumbers in their local area. At www.findaplumber.com, consumers can enter their zip code to find the nearest plumber.

For a $450 per year fee, each plumbing contractor’s business listing has a detailed description of its services and specialties, as well as customer referrals. Customers are also able to provide feedback on their experiences with the company. In addition, contractors can link to their own sites.
