Homeschool suggestions for my 11 yr old son

Having a lot of issues at my sons charter school. We already removed him from public school and charter school is close to kicking him out as well. Need homeschool site ideas please? As well as any advice.

Myself and my husband are both in the mental health field. We understand how to interact and engage appropriately with him. He has been receiving some sort of mental health services since the age of 4. Need some new ideas/advice/suggestions.
Thank you!
