Have you checked to see if there are autism specialists in your area? Or perhaps there are general pediatricians or family practice doctors who work with a lot of patients on the autism spectrum. Also, if you have something like a Birth to Three Developmental Program in your state, you can contact them to see if they have any recommendations for places where you can begin to get involved.

Try volunteering at your neighborhood school.

Occupational Therapy, but that would require more education.
