develop a mobile app -- new

I need a simple app. I still don’t know if it will be only android or both android and iOS. So please quote separatly. To sum it up, the application in question must meet the following macro requirements: 1) Section describing the Company. 2) Section describing the business (Credit for pledge, some like a pawnshop but performed by a bank) and feature of the service offered 3)Section allowing the user to submit a non-binding pledge request with the following information: • Photos of the object • Customer's master data • Note The app handles communication between the customer and the expert of Bank. The Expert's agenda is available through the app that can be used to schedule an appointment. Special attention must be paid to the management of user data that must be saved on a secure platform. You will not interact directly on the server of the final client but you will advise our expert in installation and all delivery phases.
