Are you on any of the gifted homeschooler lists? When my sons were children being homeschooled in California, I knew folks active in the LA area. It seems to me that would be a better path for figuring this out than posting on HN.

Though this is a website that was held in high esteem back in the day and happens to be owned by a member of HN: http://learninfreedom.org/

Best.
