My first response was terse, negative and unhelpful. I have homeschooled my four children (now all adults).
Others have suggested HSLDA and attending a HS Conference which are very both very good ideas. Knowing the laws specific to your state is always the first step. Really bad things can happen in some states with lots of restrictions because the laws are intended to trip you up and keep kids in the public union schools.
There are so many good curricula and there is no one size fits all solution to your needs. One of the reasons for home school is the ability to customize the educational fit for each child and for the parent as well. This is why going to a HS convention is a good idea. Lots of vendors and presentations to take in, plus being able to thumb through the books helps you decided.
It’s an educational buffet in the home school world, but all the advice in the world is useless if the parents are unwilling.
At the Junior High and High School level I preferred having an online component, especially for test taking and record keeping.
Thank you
