Care.com has a section to find tutors. All the bios also state what kind (if any) special education experience the person has. I was just looking there yesterday to see if I could find someone with spec ed experience to come to my house for piano lessons and I got 3 or 4 good leads. Good luck!

I have used that site and gotten good caregivers for my daughter as she was growing up. Worth your time.

I don't know what services are available in Charlotte but have you worked with the TEACCH program? They maybe able to help you find a tutor in your area.
