Hi! I hope that your hubby will see the light and that no amount of money can be worth sending your children to public school. Even some private schools can be hazardous to children and their spirituality (as many of them are strapped for cash and often end up with children that are "kicked out of" public school.)
I certainly understand your not wanting to waste money on a home biz that won't work.
I would recommend that you check out
She is a homeschool mom of 5 and a lead trainer in the home business industry. She has several free resources for you to listen to (she won't tell you what home biz she is involved in - so its not a recruiting site), and I believe that there is at least one telling you how to pick a home business. She also has a site called http://www.risetosuccess.com
that is her Christian site where she helps spiritually equip you to be a Christian witness in the marketplace.
I'll be praying for you!
