Do you have a plan for monetizing that would make it worth hiring a host and possibly paying out for editing and production? I currently already host one show as an "employee" - my duties are to find and book the guests (which I now have hired a VA to do), conduct the interviews, edit the podcasts and upload the content to her Audio Acrobat account. Then the owner of the show has the podcasts transcribed before she releases them. I am sure that you could find someone willing to host, but you'll have to create a business model for it and decide what your goals are and how it fits into your current operations.
I looked into Podango briefly - but decided to stick with Audio Acrobat - so I'm afraid I'm not horribly familiar with it.
