Yes, I combine the two. Mine are high school, though. 4th grade is a little on the low end for Computer classes, IMO. Can you just give her subjects she may have done together, independently? You’ll be checking them. She can start and finish at a pace which you both agree on. Perhaps beginning a morning or weekly check with her now would be wise instead of waiting until she’s older. That way she still recognizes your authority in this area (which outsourcing can erode if not careful).
Landry Academy and Inspired Scholar are the ones we’ve used.
I’ve been blessed to find and been offered Landry semesters at a significantly low cost.
My advice in addition to the daily and/weekly schedule check, give her subjects she can do independently now-history, science, and/or lit- in addition to the normal independent ones -math. Keep at least one or two -or more- like art 1x/wk for example, together. I warn not to totally turn her loose yet, as she may forget she is in a family environment and forget to develop the skills required to be patient with aothersnd toletant of others different than herself and submissive to you.
However, she may need more challenging work, faster; and she just may be a different, more driven personality than you. I think having one class online at her age would be a prudent start, something you despise teaching or grading, perhaps?
Other places I haven’t used but heard good about: Virtual Homeschool Group; Wilson Academy; LEA mentioned above. I know there are others, but my mind is gone for time-being!
