Library Consultants and Social Networking

I originally posted this on my blog Bill the Librarian and on Google Plus as well as Facebook and Twitter.

In an effort to build up my own consulting, I have been contacting companies and individuals that do library consulting. I have heard from many people in this effort. I am trying to find those that participate in and also consult with libraries in the use of social networking and social media. I am finding it much more difficult than I thought it would be to locate library consultants practicing the use of social networks themselves and promoting their use in libraries. Does anyone have any suggestions on how to reach out to that group, if it exists?
