How do you use twitter to market a business? I am trying to figure out how people get thousand or even hudreds?

There are no shortcuts. Build a website with a good service, and *good content*, and everything will fall into place.

There are of course shady people you can hire, who will generate lots of followers for you. Mostly these followers are fake accounts, russian spam bots etc, and you will pay a hefty fee. And even with all those fake followers, still nobody is actually reading your tweets.

Grow your business organically and it will be solid and robust, instead of relying on the whims of social networking.
Twitter is not some magic machine where you can just pull a few stunts and suddenly end up with thousands of customers, although that doesn't stop thousands of people from trying, but if they stopped spamming and concentrated on building their business, they'd probably do a lot better.
