I do not home school, daughter has been out for a longtime. But I have heard good things about Liberty university, it is an online course and wall builders by David Barton is suppose to have good curriculum. If you are on Pinterest or Facebook there are lots of groups on there to join in.
Online is good for some. My oldest did great with it. My youngest realized I couldn't "see" how much she was getting done and goofed off until I got the progress report at the end of the month. We went back to books for her so I could see exactly how much she was getting done.
I have a couple friends that have been using the https://allinonehomeschool.com & they're really liking it. After 15 years of homeschooling, one thing I know for sure is there is no perfect curricula. Find one that's good a enough fit for you & your student, fill in any major holes, & go with it.
