Considering you already have a large following, your best option would be to fund your shows via Patreon (https://www.patreon.com/). Many shows on Youtube, and many musicians and other artists with a following make a considerable amount of money from their fans through Patreon, some over $20k / month.

You can set it up to be either a per-month, or per-content payment, and you set up benefits to each level of donation, just like in Kickstarter.

Patreon is not very searchable, so success on their platform relies entirely on you already having a substantial audience that you can ask to get on board (e.g. at the end of each of your podcasts, and in emails, your website, etc.).

If you'd like to discuss how to best break down your funding/benefit options give me a call,

best of luck,
