Best way to get local (within 50 miles) adds?

I just became a local real estate agent - I was and still am on the side an online income person.

But I need to strum up some business for the real estate side. I'd like to get people on my Facebook page for marketing. Is there something out there that will add users, or entice users to get them to like the page?

I have FollowerLiker for Instagram from a previous IM job. I'm using that for Instagram. Is it worthwhile for FB?
