Awesome suggestion. Marketing was biggest huddle during this launch. I have been asking on facebook groups, since head of families are there, might be a good out reach?
For homeschool groups specifically, many areas will have a homeschool cooperative or resource group with a website and contact info for a real human. They're mainly there to help onboard parents who are new to homeschooling, but if you have a polite elevator pitch, they're guaranteed to at least know someone who is very frugal.
