What do you mean by "make money?" That tells me absolutely nothing about what kind of business you intend to operate.
The Internet is NOT a magical profit-source. If you have an EXISTING business, it's useful for reaching more people. You might be thinking about programs like Google Ad-Sense, but even then you need an already-existing site to use it on. It's illegal to profit from content that you don't own, so keep that in mind when deciding what content you're advertising on.
The Internet is still part of meatspace, it's not a separate entity. If you need a source of income, your best bet is to seek traditional employment.
