Android Mobile App for Business Application

We have an application developed in YII 2.0 using PHP 7.2. Need to get an Android Mobile App developed for the same. There would be 4 user roles in the app, viz. Admin, Sub Agent, Sales Person and Airline. The Sub Agent would be able to do the following functions - Add New Bookings - List and View Bookings - User Dashboard The Sales Person would be able to the following functions: - Add New Sub Agent - Add New Booking for a Sub Agent - List, View and Change Booking Status - User Dashboard The Airline would just have a Dashboard showing the performance of different Sub Agents in the system. The Admin would also currently have access to his own Dashboard. Later we would need to add the following features to the Admin role: - Add and Manager Sales Person - Add and Manager Sub Agents - Add and Manage Airlines - Add and Manage Bookings The above functionalities for the admin are not required as of now. There would be 3 types of Bookings in the system: Single Booking ([login to view URL]) Regular Movement ([login to view URL]) Multiple Booking ([login to view URL]) Single and Regular Booking would create 1 Booking in the system when the form is submitted. Multiple Booking would create multiple bookings in the system when the form is submitted depending on the number of time the + symbol is clicked. The Dashboard for the various users would primarily contain info boxes, charts and graphs for the various data items the user needs to see. (see [login to view URL] as an example) All the APIs required for the Mobile App would be provided. This Mobile App needs to go live on Mar 20, 2019. Please bid on the project only if would be able to complete the project in the said time frame.
