Apps inviting friends on Facebook

Apps inviting friends on Facebook I want someone to guide me how or suspend it for me: - An application that shows me which of my friends on Facebook (available or able to order) as best friends to join ... The idea is: I want to do my business page ... So every week I give a gift to a friend on the most he could invite friends to join (for example I give him 10 points for each member as he could) ... Thank you
