Possible? Of course! With hard work and effort, everything is possible! Easy? It really depends on how you promote yourself, the people you're targeting to, the product itself and its price.
Facebook now has an option to share the stories you like and pay for it (that's what they call sponsored stories)! That's a way of promotion as any other, like Facebook's ads. Of course, you can do lots of things to promote your business and get to your goal... but the very first thing is to create a Facebook page (careful, I said page, not profile. Profile is what you use as a person that wants to get in touch with friends. To create a page, you need to have a profile first . Also, don't confuse it with groups which is the third type of page you can have in Facebook)
