you hit the nail on the head when you referred to your own DS as having a PTSD reaction to school.  I haven't been able to get my own to articulate his issues with school but that makes perfect sense to me.  I have put out feelers for homeschooling groups and just had not had a lot of luck finding any.  I live in a very locally inclusive area and if your not from here (which I'm not)  being included into the "mix" is hard.  
I have thought about about a HS student doing some tutoring.  How would I go about finding one?  I don't want to sound silly but really, do I call the school and ask?  
Thanks so much for taking the time to respond!!!
