The secret of online business is that:
a) most people you hire as a contractor are frauds that will take your money and give nothing that you can use. So be very careful and test them with very small projects to begin with. Think of it as money you can throw away if they just steal it from you.

b) Web sites that rank on page 1 of Google have an huge investment in a website and in getting links. Don't think that you can get to page one easily, or cheaply. And, if you are not on page one, you may not get much traffic from Search engines.
