Have you considered adding a Twitch stream of the show for another potential source of income? While Twitch is mostly dedicated to streaming of games there are a number of talk show type formats achieving success on that platform (i.e. H3H3 Productions).
Twitch is owned by Amazon, which isn’t great considering the latest development with the former affiliate program, but it does come with one benefit that should not be ignored. Anyone with Amazon Prime has access to a free Twitch subscription token they can use to lend financial support to their favorite Twitch channel. I am positive there are a number of listeners, myself included, who have Amazon Prime and would be happy to send “free” money FTL’s way if there was a Twitch channel available for their free subscription token.
Worth considering,
