Assuming you already have a fan page in place, what works for me is to connect with other fan pages that share interests..try to think outside of your immediate circle of customers and think about what other pages they would have already liked. Some suggested pages are ones about fashion, trends in jewelry, beach destinations (I'm in Hawaii but if you live in an area that is frequented by tourists try searching for pages about your local attractions)..also pages like moms to be (baby stuff) , goddess, new age, shamanism, dance, etc.
Not only can you exchange likes with these pages but make sure you frequent them often and interact. Many of their visitors have found me as a result and liked my page.
hope this helps
