Simple iPhone/Android App

I need an app built that is a property score card app, quite simple... people open the app, search the property address (bring it up in google maps) select that property and start a Score Card process against that address, the scorecard process is 10 - 20 questions about the property, they score the questions 1 - 10 e.g Area/Position of Property - choose between 1 - 10: Distance to CBD = 7 Transport =10 Shops = 5 Interior - choose between 1 - 10: Kitchen Size = 4 Masterbedroom Size = 2 At the end of the form they get a property score based on the answers and a button that says, do you want a real assessment done on this property, hit submit, they fill in some details and the form comes through to us to contact them. All questions and specs will be provided.
