Sounds like you are off to a great start. In order to make the phone ring, you will need to develop a marketing plan that will continue to amplify your reach. Here are 3 things that quickly came to mind:
1 - If you are already on social networks, are you connecting to groups and sharing your information and/or posting snippets of the podcast to gather interest?
2 - With your current followers, what can you do to have them advocate for you? Use your list to provide opportunities for others to connect you to more coaching clients.
3 - Connect with others in your field that can enhance your coaching offering and develop a mutual alliance or strategy to share resources, lists, create a bundle package offer.

I would be happy to brainstorm more ideas with you and develop steps to implement. Understanding the focus material will create more steps. Let me know how I can help.
