You ought to very seriously consider reversing that order. We looked into Christian schooling and decided against it for a variety of reasons, the primary one being money.
Find out whether there are good homeschool support groups in your area. That will provide a lot of extra-curricular activity for the kids and perhaps the opportunity for homeschool co-ops.
Christian schools are definitely a better option than public schools, but the amount of time demanded to help the school in fund raising and cafeteria duty and janitorial duty, etc,wasn't worth it. There's WAY more freedom homeschooling. You set the schedule.
My kid brother, whose educational options my Christian mother was able to consider on their own merits once my Marxist Atheist father passed away, was privileged to receive a Classical Education at a Reformed Episcopalian academy (all the "liberal arts", PLUS Greek, Latin, Logic, and Rhetoric) for only a little over $300 per month. Barely over one-third of what the Government "charges" for its Government Schooling "services".
We'll consider all options, but I really admired my kid brother's education. It's a consideration, y'know?
At any rate, even if we do go with our first choice of Christian Schooling, we don't intend to just stick 'em in class and forget about them. We'll try to at least supplement their "formal" schooling with home instruction, as well. I Promise. ;-)
