Sounds like it might be helpful to have a "how to sourdough" book for different profiles of people/families. like how much time and attention do you have to offer and how much/which kinds of product/output does one want. Then people can identify with one of the profiles and focus on the content there.
1) busy family - how to get started with minimal effort
2) busy family - how to make a lot while already busy
3) total novice - basics
4) total novice - want to have sourdough everything and have lots of time and attention to spare
4) master baker
5) ... Who knows.
