Could you expand on the "school" part? This sounds fascinating. Are you training other would-be farmers on organic methods?
Once you get to scale then you need to start worrying about how to keep the animals watered in the dead of winter, how to extend your growing season, how to prep and store your produce over the winter months when you can't grow fresh. These all seem like tiny things when you think about them individually, but they quickly make people panic and go running for the nearest grocery store.
