Android tour guide application

I need tourist guide application for Android (later I will order app for Iphone) that downloads data about attractions, places, events and routes/guides from a web server and displays it to the user. You need to set-up website (WordPress) with database and a simple web interface for data entry. Users could register on my site (Free or paid) and enter their places / tourist attractions / events (location/picture/video/txt/price/link) and Routes/Guides (routes between places / attractions). Users must be confirmed by admini. The app also utilities: - user location - Google maps to display: a) nearby custom places b) routes
