Android app development for smartphone & tablet (URGENT!!)

We are looking for an experienced and reliable Android developer who can build an physiotherapy application for the android platform. The app has already been build for IOS and is called 'Pocket Physio', it is currently available in Apples app store. This now needs to be converted to work on smartphones and tablets using the android operating system. There will be no design or functionality changes, just a straight forward rebuild of the app for the android platform. The app features video exercises for patients recovering from hip and knee operations. All video can be supplied in whichever compressed format is required. The app features an appointment reminders section where a reminder can be set up for either an appointment or exercise routine and is done via push notification. All artwork will be supplied as .psd files. Please download the app from the App store to see exactly what is involved and get back with your quote as soon as possible, this is project ready to be started.
