Competitor analysis/marketing/social network analysis

We are looking for a freelancer who is able to analyse social networks. The goal of this project is to identify important introducing brokers (IBs) in the foreign-exchange (fx)-market, especially IBs of our biggest competitors. What are the characteristics of an IB and where do you find them? Practically every fund manager with clients interested in fx trading is a potential IB. For that reason fund managers need the services (trading platforms, etc.) we provide.
