Facebook marketing trick required

Dear Freelancer, we have a Facebook fan page and want to promote this page more. By using the Advertising function in Facebook we recognized that the Region and City of the members are tracked and can be used for that. Now we are looking for somebody to get us a list of Facebook members in a specific region who we can invite personally to our fan page. Maybe you have a trick or tool already or we have to develop something with you... Please write your ideas and expirience in this area in a private note. The most feasible idea gets this project assigned. Thank you DJ Business
