This is the same as someone saying:
I want to start being a surgon, but i have no idea where to start or how these thing work. Also I saw few ppl on facebook that they're getting money for being a surgon or something-i want to try that also.
Professional web design is a highly skilled profession (although there's a lot of hacks that sell awful work, and some people are uneducated enough to get taken in by them).
If you want to be a professional, you learn to be a graphic designer, and learn to apply your skills to the web. If you have not been able to use Google to access all the skills online that you can teach yourself, you'll probably have to go to a school to learn.
But quite frankly, web design is not a profession that you succeed in if you are not a self starter and can't figure out problems on your own.
If you're serious about making a living, figure out what you want (no "or something") and go after it with all your energy and you'll do fine.
But as long as you noodle around without focus or ambition, you CERTAINLY won't get anywhere in this field.
