Not to slam your ideas, but it sounds like you're getting in over your head here. Not to say that you couldn't do it, but unless you have some sort of a nich to exploit, you're in for a really rough ride.
Not only is the market saturated with exp. web designers that will work for food, but there's a ton of programs the build them for you for like $20/mo, and everyone and their brother is trying/tried to start a web design company (even me
).
It's a pain in the ass, and not worth it anymore unless you can score some major clients. Even then, you'll have to have some bad ass skills, or fill some kind of need that no one else can to make the green.
But if you're determined, then I wish you the best of luck and hope that you kick some ass.

ps. Don't learn anything...find someone else that already knows it, and just pay them to do it. You'll save yourself a ton of time, money, and headache.
