Campus Map app using Bing ( android and iphone app)

We need an android and iphone app. The app is simple when we currently see our University Campus through Bing we see a birds eye 3d view of the buildings all we want to do is have an app where each building name when clicked shows the user where on campus that building is.( Bing already does this when we look up the building addresses respectively) It should also show more pictures of the building which we will provide as well as ask the question which building are you near right now. For example if the student is near building A and wants to know where building C is then the map would high light a route or just show building C on the map. That it!
