Support to find 19 year old work

Good afternoon.

I’m new to this and hoping someone can help me because I’m at a loss. My son is 19 and has autism. He can interact with others and has developed good coping mechanisms. I’ve spent most of his life handling everything myself and not really accepting support. Now I’m at an impasse as we try to get him into work, but nowhere seems willing to take him on. He passed his GCSEs and a Level 2 course at college. He clearly needs extra support and doesn’t always understand things the first time, but companies these days don’t seem to want to bother. I need him to be able to live independently. I’m feeling so overwhelmed and upset with myself that I can’t make it happen for him like others his age. I feel like I’m failing him.

Getting a job is literally the last step we need to take.

Any advice or any links to places you know may be able to help us would be brilliant.
