I would build a handicapable/neurodiverse arena to host not only Special Olympic and sporting events, but big named entertainment concerts for the public as well. Inside the building there would be offices of occupational, speech and language, physical, individual and family therapy, with funded arts and crafts activities, availability for respite to the family of care givers (from infancy to elders). Vocational opportunities for all, great way to volunteer hours, great way for local companies to participate and advertise. Medical staff on site. State of the art handicapable playground on the grounds alongside a an indoor/outdoor therapeutic and swimming pool. Sponsors from Autism to Alzheimer associations.
I would call it the Oβrena. A name an Autistic client called me. Dream big!
Is start a little woodworking business, making custom furniture.
a music studio. will find musicians for a band and record my music. the album name "Puerto Rican Hopes, Cuban Fantasies and American Dreams".
Oooo, this is a tough one. I think a shelter for homeless LGBT+ youth. It's not really a "business" but I can use this money however I want. Sustaining it would be another thing though, but that isn't what this question is about!
I'd start a worker-owned co-op to rival the world-sucking Amazon.
