online business, is it the really good?

Tweet

I work hard to raise my family but unfortunately my earnings can't cope up our needs. A friend of mine suggested to start an online business for a little investment. But I'm doubtful because I might fall into a fly-by-night business and end broke inspite of being eager to start a new one. If you would mind can you give me an idea on what kind of online business to engage nowadays? Where and how do we know that it is a legitimate one? What are the dos and donts of engaging an online business. Your suggestion is highly appreciated, thanks.
