I just found out that the state offers help in getting your disabled child a job. There is a lot of assistance out there if you know where to look. My daughter is disabled, and I found out the Department of Rehabilitation offers a lot of help transiitioning young teens to adulthood.
They help with jobs even when they are in high school. My daughter works for our city as a clerk, and she makes good money. I did not know this program existed. It would help all kids but just disabled kids are eligible.
Google your state's department of rehabilitation if you need more information. I live in Oklahoma and if you need more information from this state email me, and I'll email you what I know.
