Hi Becky,
I do similar programs at my library in Montana--am planning on a summer of homesteading during 2023.
Some of the ideas I have tossing around are:
Composting basics
Cheese Making
Raising Chickens
How to butcher
solar panel basics
beekeeping
I'm not sure where you are located, but many of these programs I have sourced for free from knowledgeable individuals who were happy to come in and spread knowledge or drum up business for themselves and their farms.
On another note, many of the videos you are thinking about presenting would fall under "educational" and do not necessarily need to be licensed to present at the library.
