I would search on the Internet under "free homeschooling". It will take some time and patience on your part but you should be able to find quite a bit. Bookmark any page you find.
Also, find out what your daughter is the most interested in, go to your local library and have her check out everything she can find that has anything to do with that subject. The sky is the limit when you start homeschooling.
Our son is now 14 and is trying to earn some money because he has found a gemology course he can take. We told him if he pays half then we will pay the other half. I contacted the school to see if there was a minimum age and they sent back a reply saying that they had somebody as young as 13 take the course. So, if he gets his part of the money earned we will pay the rest.
You might see if there are any special scholarships out there for children of parents with breast cancer that may help you pay for something. You would be surprised what kinds of scholarships could be available too. Hope this helps some.
