I admire your passion, but getting some attention from a gaming company is very very hard.
If you really want to do it, you first need to compile all your informations in a technical document. Make it as professional as possible and make sure it's clear and organised enough so that anyone could understand it. It should start with a little resume of your game and it's working, and then get as technical as needed.
Then if possible, ask a trustworty teacher if he can spellcheck your document. This is really important, you want your document (and so your game) to seem as professional as possible. You also need to sound professional. No begging or sucking up.
After that, make multiple copies of your document. Send one to yourself first, but don't open the package once you get it by the mail, as the stamp is your proof that you really had it by that date, just in case someone try to rip off your idea. Then send a copy or your document to every game company. Try to do some research so that you can send it to the right person. YOu can also send your document to individual rpg games developpers, if you can manage to get their adress, and ask them for help.
This is the best solution I have for you, and it's still very unlikely that you will get any responce.
If you want to feel safer, you could copyright your document, but that cost money. Just sending a copy of it to yourself should protect your intelectual property, unless the other person can prove he got the idea before you.
Edit: In my opinion, the company that is the most chance to listen to your idea is probably
Valu-Soft. As they release lots of games, and usually are not as hard to please as the bigger companies.
