An Android App for Tourism in Ghana

We are a travel and tour service providing company in Ghana, we seek to develop an android app that will have details of tourism in Ghana, have the option to book Hotels, Tour Packages, Vehicle Rentals, and other services relating to tourism. When the user makes any booking; we would want the request sent to our email address, and the senders email has to be automatically picked from his or her gmail account registered with android, so that we always have a correct email address. The app will have few "Views" and "Viewgroups" We would like similar projects like: TouristEye Labtrip Travel Guide It will be a free app, mainly about tourism in West Africa!
