Is it too late for him to apply to the Think Summer Institute? If not them, then perhaps Summer Institute for Gifted overnight camp?
I think that getting him out of his social environment sounds like a terrrific idea.
I would check around and see if there are any psychologist who serve as educational consultants to the school that the school "likes." I would guess that you're going to need a "Professional" of some kind to go to bat for you at these meetings.
Another alternative is community college courses. Online college courses work for some.
You're in a pickle, so I'm sending you ((hugs))

What are your backup plans? Have you considersed private school? Homeschooling? You'll be a better negotiator if you have some alternatives that you can live with.
