Mobile Application Development

I need to create an app for both android and apple stores. The mobile app will function as a property listing, instagram style, where you can snap a photo of the property and upload it on the app. the mobile app must function as follow: - content of app to sync with website, and vice versa, and content from app possible only upon login - account login possible both on website and on mobile app - purchasing credits possible through google playstore or apple store The mobile app must look vibrant in terms of design and functions. The colour scheme must follow skype's colours with a little bit extra. We will only provide you with the logo - you will have to develop everything else about the app from scratch or from other sources.
