Outsourcing math and sciences

[CleoQc]

I'm looking at options to outsource math and sciences for my son, who will likely be able to tackle grade 9 next year in those subjects.
I want a secular source, with teacher interaction, and grading, so that I can be hands-off. *and* deadlines..

I'm looking at K12 and Clonlara. Are there any others that are fully accredited?
Any horror stories? Any success stories?

Is there teacher interaction at Clonlara?

I've looked into Clonlara because I am afraid that the NCAA would not approve all of our high school selections. But, I would just use them for accreditation. It doesn't look to me like there is teacher interaction.

Here are some I've looked at:
Derek Owens (http://www.derekowens.com/0910/index.php)
This is appealing to me because it's a real person albeit via video, but they do homework and grading and deadlines. I am not a fan of computer based learning.

AoPS (http://www.artofproblemsolving.com/Classes/AoPS_C_About.php)

Apex (http://www.apexlearning.com/Home.htm)

ChemAdvantage (http://chemadvantage.com/)

ScienceJim (http://www.sciencejim.com/)

I don't know about accreditation for any of these.
