Pick up phone and call head of HR and ask if they are working with a relocation company, if so which one, if not ask if you can send them some materials on your company/services.
Have you worked relocations before? Transferring executives and employees want to know lots of information quickly about your area -- best schools, best neighborhoods, best countryclubs, best golf areas, best spas, best restaurants, social events, areas to avoid, crime statistics, etc., etc. You need all that information at your fingertips. You need to make them feel comfortable with the area, not just you. It's more involved than just running some searches in the MLS in a given price range.
