(I was also skeptical of the post, but I chose to respond in the case that it was a legitimate request.)
We have had a few motivated 12-13 year old kids in the past who have produced good runs. The way most of us got involved was to simply pick up the emulator and start working, which might be difficult for someone so young.
If you truly are interested, the best way to get started is to just dive right in. Most of us simply started out by download the emulators and recording some input. Our site generally tries to be supportive of constructive questions, but we hope you look through the documentation and have at least tried to fix your own issues before deferring to us. The documentation doesn't always cover everything, but we would hope that it is tried before asking someone to go out of their way to help.

Of particular note: This site will not supply roms (games), or tell you where to get the roms. We only supply the emulators used to play the roms. Downloading games is a questionably legal activity, but many of the games we play are old and many of us own copies of them anyway. It is not illegal to rip your own copy of your own game to your computer, but some of us don't have the device to do that, so we get them online.
This site also does not support many of the newer generation systems (PS2,PS3, Gamecube, Wii, Xbox, Xbox 360) yet because the emulators are not advanced enough.
With regard to coding: Coding is something that takes a while to learn, and we probably can't offer the effort necessary to help someone to learn from scratch. Coding isn't terribly essential to many games. Many games can be performed well simply by monitoring the character X position, which is pretty easy to access through the emulator.
Just to give some perspective on the tutoring. We currently have around 1700 published movies on this site, produced by around 300-400 individuals. Most of the non-Japanese population that produces TASes get them published here, so it is probably safe to assume that the number of people in the United States and capable of helping is less than that. A large portion of the skilled TASers are over 18 and either in college or holding a full time job. The odds of someone being nearby and interested are extremely low.
This is probably more of a hobby than a learning experience until one starts advanced coding to perform more difficult runs.
Hope I was able to supply some useful information.
