K.C.
I'm guessing you have a business that you are moving to facebook and are looking for fans on there.
Facebook does ads that you can target to the client you are looking for (ie; mothers in ID between 20-45) they are pay per click ads and were pretty successful the couple of times that I used them. I just set my daily $ limit and then Facebook pulled the ad each day when I reached that amount. Some days I reached it in an hour and some days I didn't reach it at all. Most days I reached it pretty quickly.
Another idea is to "friend' similar pages or find pages thats sole purpose is to promote other pages and find out how they work (Mommy of 3 Peas, 411 on your favorite boutiques, Izzy B; to name a few that I follow)
Good luck!
