podcast promotion

I have a very well-researched, professionally produced podcast with 25 episodes so far, and I'm looking for a freelancer to help get it in front of more people. The show has a progressive bent and my target audience is interested in politics, history, and current events. This is a high-quality podcast in league with the content of the Meidas Touch and the David Packman show but it is currently audio only. I'd like to find someone who could pursue effective promotional strategies that would reach a larger audience.
