I homeschooled my first 2 children, and then after my divorce, I found a Christian private school, where I kept all the kids and taught there myself, until I couldn't afford it any more. My oldest was going into 11th grade when all the kids were moved into public schools. But I sure enjoyed homeschooling them and working in the private school. But teachers don't make enough money for all they do, and I had to go out and get a job that paid enough $$ to get all my kids through college. I was fortunate in finding one, thank goodness, because I had 3 kids in college at the same time!
I'm in Florida, less than an hour inland from your location, and have checked on all the farms I knew of, back in the day around our area, but most are gone now. There may still be a few in up in Lakeland County -- I don't know them, but I think their name is Encore Farms -- or in the Ocala area. There's one I just can't think of the name for, and they were also trainers and showed one of my stallions, but I only used them for a year, and it was more than a decade ago! I know plenty of farms outside of Florida, but that won't help you. There was a mini farm in Sarasota, but I think they changed to Shetlands, and I don't see them still in business when I do a google search. Sorry I can't be more help.
