App Mobile Application for logistical Services

I am looking for a mobile app developer to create an app for logistical services, to be developed for the Android/iOS platform. The app should contain transportation services, with a user-friendly interface that is accessible to the average user. It should have all the necessary secure payment options, allowing fast and easy transactions. Moreover, it should allow users to track their orders using GPS, so they can get an accurate prediction of when their order will be delivered. This app must be developed with low bug potential and must provide a rich user experience. Finally, the app should be highly customizable, allowing further services to be added in the future.
