Does anyone know any place in Northern New Jersey were the property taxes are not sky high?

My Son attends a private ABA school in Northern NJ. I wish he could also attend their Adult Program . We live in Staten Island. I do not trust the Programs here.
I know more about working with Autistic people than all the NYC Teachers and Psychologist I have met. I simply distrust what the Programs are telling me. They dislike my questions. They seem to fear my intelligence .
The NYC Public schools do not do ABA( Applied Behavioral Analysis ) . People that are not familiar with it fear us that are. They know no matter how much they attempt to deny it our method is appropriate and works. When the Adult Program Social workers here where my Son goes they BS me. They become uncomfortable when I am not dumb. Can anyone help me?
I know some good Teachers really care. Like the ones in my Son’s school. Please help if you can.
I can not even find anyone to help over this long break .
