Podcasting beginner tips

I am considering to start an educative podcast in a couple months (just considering, nothing certain). I want to monetise it with a freemium model where the most elementary thing---the audio---is free or very cheap (e.g. $1 on Patreon), but handouts (non-essential but very useful) are slightly more expensive. It will probably be weekly to begin with, and I mgiht add some extra material if it will be viable financially. I can't really afford pro or prosumer gear at this point, so I'd like to avoid that if possible.

My question is, what are your tips for a totally beginner podcaster like me? Either my case directly, or a more general newbie with little funds tobdedicate to this in the beginning.
