I was recently doing research for a client and ran across GetListed.org. It is one of those cool little tools that saved me so much time and energy I knew I had to share it with you. From their "About Us" page:
Since launching in January 2009, GetListed.org has helped over 1.3 Million U.S. small businesses take control of their online presence. Our primary offering is an easy-to-use online tool that makes the process of claiming business listings at Google Places, Bing Local, Yelp, and other prominent local search engines more efficient.
GetListed.org currently focuses on businesses based in the United States, Canada, and the United Kingdom, but additional international versions of the site are in development.
We're advocates for search engine optimization best practices that will lead to sustained, long-term search engine rankings for small businesses.
