Looking for Podcast Co-host

[rookiebatman]

I recently started a podcast where I (an atheist) have discussions with a friend (who's Christian) and we have kinda good-natured debates about religious and theological issues. We've recorded six episodes, and I was really enjoying the chance to think through the positions I hold and see how they hold up against an opposing viewpoint, but now it looks like my co-host may not be able to continue. Even if he can, though, I'd still like to be exposed to more than one opposing viewpoint, because he hardly claims to speak for all of Christendom. Does anyone have any advice or suggestions on how best to get the word out that I'm looking for a theist to co-host a podcast with me?
