Online Coaching App Development

I'm looking to develop an application for our online coaching center, accessible on both web and mobile platforms. The app should support students, teachers, and administrators with the following features:

Live Sessions
- Conduct multiple live sessions
- Automatic recording facility for live classes

Course Management
- Upload pre-recorded classes
- Course purchase functionality

Assessment
- Test paper creation and management

Payment Integration
- Support for Credit/Debit Card, PayPal, and Bank Transfer

Please provide an exact quotation to avoid unnecessary discussions. Ideal candidates should have experience in developing educational applications, strong knowledge in secure payment integration, and a good understanding of live streaming technologies.We will only proceed with price that you have done in bid. Don't make false bid or base bid on this project
