I think in facebook likes you can just get the likes but not the business for your company.
Buying likes doesn't really helps much rather you should pay for advertisement which can be a much better option
I know Facebook is a great tool one can be used for marketing purposes, but I am not sure if buying facebook likes is a good idea at all. From my point of view, this will only generate irrelevant likes, and will offer less business to none. Gradually gaining genuine likes is still the best way to go.
