I was delighted to find the nearest Sylvan Learning to me had a tutor who homeschooled her (likely PG) kids and was active in Mensa. She and my son hit it off and she was just amazing with him. She does tutoring by Skype too last time I asked. I can PM her website to you if you're interested.
I looked up alternative writing processes to find one that helped my son see where he was getting stuck. The Cognitive Process Model was a good fit for my son. I had no idea there were multiple writing processes proposed until a desperate midnight google session. Finding a different writing process model was a breakthrough!
