Android app UI redesign project

Hi, I am looking for someone to help me redesign the UI of one of my app. The application target users are both parents and kids so UI has to be appealing to both the target users for the relevant screens. The UI need to be designed in a way that it can work with both phone and tablets; portrait and landscape mode and devices with all the popular android device resolution and screen density. NOTE: I will do all the coding so I just need the layout XML and any images you would create. We can work together on integration piece for dynamic content. Here is the link to the application on android marketstore to give you an idea about app and current UI: [login to view URL] Its a free app so feel free to download and check out all the screens. Thanks, Paresh
