Yes, it is a good option but I think you should really be wary of these sort of practicing of purchasing likes. You never know when the Facebook algorithm will change and they may start penalizing pages that have done this sort of thing. Kind of what happened with many sites that were purchasing backlinks for SEO purpose. Google penalized them and banned their sites.
I manage a page for my call center services company and I think slow organic growth is better than purchasing likes.
