Android app for digital menu

We already have an iPad application similar to [login to view URL] or [login to view URL] Please go through all its features and screens before bidding. Ours is not yet available in the app store. We need an Android application developed similar to our iPad application. Also we need guidance regarding the tablets the app will run on as there are so many kinds available these days for different Android versions. We need an Android developer to develop and maintain the same for us. It's a business application and might need a little bit of customization for every new client. Please show us your portfolio to make it easier for us to choose you for this long term relation hopefully. Please note that the server side development has already been done by us as our iPad application is in working condition. You are required only to design the Android interface.
