Writing Tutor For Neurodiverse Kiddo

My son is 12 years old and in the 7th grade. We're homeschooling now, because even with an IEP, his school failed him miserably. E lost all confidence in himself as a result. E is high functioning Autistic and has Executive Function disorder, but he is hard working, creative, and bright. Writing is the area he struggles with most, yet received no help for. I'm hoping to find someone who is kind, patient, and can work with E 2-3 times a week (depending on cost). He thrives in a 1-on-1 environment and when work is broken down into manageable parts with clear instructions (checklists are key!).
