Add Today's Widget to an existing iPhone App

Oyster Balance and Refund Widget Addon I am looking for an objective c developer to add a Today’s Widget to an existing app. The widget will work with the app (our app is already on iTunes Stores) to show user card details on today’s widget view on users device. You need to call a service which will return cards data in an XML format. You only need to read the XML and create a widget view for that XML data. Widget will work as a quick view of information and is linked to our main app with a user primary key (PID). User can tap on the widget data to open our app. The user will login to the main app to check his card balance. I will provide you everything you need including web service URL, sample XML with, widget look and feel and you only need to create the widget and integrate it in our app. Please provide us your previous widget work examples. Please only bid if you have reference to your previous widget work. Please specify your timeframe. Thanks
