I do think that 'help rich people' sounds more like a begging letter than an enquiry about the future development of an infant who currently has unusual talents.
OP: as you child is so young, it is impossible to assess what's going on. It'll be a good few years before potential really manifests itself.
Until then , you need to keep doing what you probably already are doing - talking a lot, reading to him, discussing what you are reading, taking to museums, exhibitions etc.
If you can, you should start saving now for private school (compound interest will help, and if you cannot secure a full bursary you'll need to find your share of the fees somehow). I can't think of a body that pays for children to attend mainstream private schools (other than charities which can support in cases of bereavement affecting existing paying pupils, terminal illness of fee-payer, and the like).
So the route is means-tested bursary (which is not the same thing as a scholarship). For these you apply to the school. You might want to register him speculatively now with all the private schools within reasonable commuting distance, just in case, but you do need to look to see if they offer bursaries at all and if so from what age.
Also if what you want is more money, to the tune of several thousand per year, can you change jobs to a higher paid field (as your DS is barely out of babyhood, you have time to retrain), work more hours, take on a second job, have a lodger etc?
