Buena Highschool has a homeschooling program. I am pretty sure most public schools will have them, you just have to talk to the counselor about it. I'm also think it's free since it's through the public education system.

Most of the free online school programs have limited enrollment and/or wait lists. Some of the ones you have to pay for may allow enrollment in the middle of the semester. Otherwise, you will have to wait until the next enrollment period. I think some are beginning enrollment now for spring semester and next fall.
