iPhone/iPad App update & conversion to Android App for phone/tablet

We already have an iPhone/iPad app (ios7) but we need additional functionality added to it. Currently, all user data is saved to the device. We want to updated the app to offer a choice of were the user can store the data. The new functionality would give the user three choices of where they would like to store their data. The three options would be 1) on the device, 2) store on iCould and 3) store on Dropbox. This updated will need to give the user the ability to sync the stored data seamlessly between another iPhone or iPad running the same app when they have chosen to store that data with either iCloud or Dropbox. Also we need this app converted for use on Android devices. It will need to have all the same functionality as the updated IOS version but without the iCloud support. The Android version will need to give the user three choices of where they would like to store their data. The three options would be 1) on the device, 2) store on Dropbox and 3) store on Google Drive. This updated will need to give the user the ability to sync the stored data seamlessly between other Android devices running the same app when they have chosen to store that data with either Dropbox or Google Drive. The app will need to work on both the Android phones and tablets. We need this project to be to be iTunes and Google Play store ready with no code errors.
