My kids homeschool, and they do it for real, so these guidelines refer to them -
I am the counselor. I create a transcript, write the counselor letter and fill out the school form. I also do the homeschooled supplement. For the two recs, she used one online teacher, and a math prof at a local university who runs the high school math circle that my daughter has been involved in for the past 5 years.
If 100% of your classes are through the online school, then I would have the counselor create the transcript, the counselor letter, etc. I would ask two tutors who know you best to do the recs. If you have taken any local classes , maybe at a CC, I would ask one of those teacher is that works.
I think the HSing form would be your parents or your job, but here is the tricky part - it should be sent in with the counselors stuff, either electronically or by snail mail. (to get it electronically, you need to enter your counselors name on the common app school form section - that field becomes visible only after your finish a particular section of the CA, but I cannot remember what it was...) So you will need to furnish your counselor with the information needed for her to fill out the forms. It is not a difficult form.
