Android and Iphone App design - Small Simple APP

Hi there we need a small simple APP created for our local town. The APP should contain: 1) Main page listing categories: Categories are: a) "Fine Dining Restaurants", b) "Activities", c) "Shops", d) "Art Galleries" Each category page would then contain content related to each category. 2) Within content users should be able to click on a location name (e.g. Restaurant Name) and shown the location on Google maps. 3) An advertisment banner at the top of the APP on every page. 4) App should have a seaside/beach and a luxury look and feel to it. Any questions just ask.
