android mobile app

Hi, I require quite a simple mobile app developed. the app will have x screens 1, login screen: username/pass 2, menu screen: add data, view data, search data, settings 3, add data: simple form to add data which will submit to an existing website database 4, search data, a form where you can enter data and it will search an existing database and display results 5, view data - view one of the results you just searched for 6, settings: turn on/off notifications if notifications are turned on, then the app is to run in the background and listen to all of the inbound calls, if a number that is calling the phone matches a number that is stored inside the app database it needs to flag a notification with the record details (search the db on each inbound call for a match to the telephone number). please only bid if you have experience in building this type of app with phone book interaction and can fully develop, test and submit this app to the play store.
