I need a new app developed

General information for the app: The app is a book. This will also be accompanied by audio capabilities feature.
Kind of development: New app from scratch
Description of every page/module: The app is a book that users can download. This could also be accompanied by audio capabilities to assist with pronunciation.The best description of this app will be like the Bible. You can search for chapters, names, etc. The app will not be complicated. It is basically a book that is made available on an app. There will definitely be some additional features to this app in the near future but the basics have to be done right. Happy to chat more with the best app developer on this project.
Description of requirements/features: The features and functionality MUST include being able to search by Chapter, Name of person, place. This is basically a database-based app. This app needs to be available across Android and iOS.
Extra notes:
