Online Class Management Platform

Project Description: Online Class Management Platform
I am looking to develop a simple platform that will allow me to efficiently manage my English classes. The platform should include the following features:
1. Class Schedule and Booking System
•    An interface where students can view my available class schedules.
•    Students should be able to click on an available time slot to book a class.
•    Once booked, the class should be automatically registered in the system.
•    I should have access to a daily list showing the students who have booked a class and their scheduled time.
•    Rescheduling system
2. Payment System
•    Integration with different payment methods:
o    Cryptocurrencies
o    Western Union
o    (Optional) Credit cards
•    The system should record each payment, including:
o    The amount paid
o    The payment date
o    The payment method used
3. Student Management
•    A section where I can view each student's details, including:
o    Name and country
o    Contact information (phone number and email)
o    Payment history (amount, date, and payment method)
4. Private Chat for Each Student
•    An internal messaging system where I can communicate with each student individually.
5. Automatic Time Zone Conversion
•    The platform should display class schedules according to each student's time zone.
•    My availability should automatically adjust to the student's local time, based on Buenos Aires (Argentina) time.
Technologies and Platform
I am open to suggestions on which technologies to use, but the platform must be user-friendly for both me and my students.
