As said above, move coding these days gets outsourced to India. But that does not mean you can't still earn some good money from it. I am freelance and find most of my work comes from word of mouth, once you have a few happy customers you then get most work from referrals.
I think it would be better to go to college if you can and with the build up to going to college you could always use something like
http://www.codecademy.com/ in the mean time.
If you like creating things I think its a great game to be in, to take someones ideas and then turn them into web pages is always a good feeling.
Best of luck with it all and if I can be of any help just let me know.
