I am looking for the names (and contact information) for the authors
agents that have in the past represented Tom Peters.

I have written a compilation of pithy business with Mike Smock the
founder of Vsente.  See:
http://Gurured.com

Heath Row of Fast Company described the Guru Red Rules as a
"thought-provoking read... full of energy, insight, and advice."

We have been referred to a business book publisher, but I would like
to retain a professional agent and do it right, with some professional
advice and direction.

I would like to call these agents to see if they would represent us,
but I don't know who they are or who to contact them.

I am not a registered researcher, but I know the answer to your question.
