Android and Apple app development

We are wanting to develop a mobile app for use on Android and iPhone. Our client runs a British daily deals site which is now wanting to move the business onto a mobile app platform. The app needs to work very much like the app used by [login to view URL] Please take a good look at the above app before bidding. To keep the bidding process simple please bid based on producing an app which works in exactly the same way as the one used by the above site as it has a lot of the features we require on this app development. The client is open to either connecting up the app to the existing site via a data feed or developing the app to run off a separate admin system to load the deals onto. Payment will be made on successful acceptance onto the Android and Apple market.
