Ready-Made Online Tutoring Website

I am looking to purchase a fully built online tutoring site that I can see working in a live demo before committing. The platform must already support both one-on-one and group classes and include an integrated meeting link with automatic recording so sessions are archived without extra setup.

Core functions I need to see in action are:
• Live video sessions with stable streaming quality
• A scheduling / booking calendar that students or parents can use on their own
• Built-in payment processing (credit card, UPI, PayPal or similar) so I can take fees immediately

Teaching tools should be part of the package, not add-ons: an interactive whiteboard, reliable screen-sharing, and straightforward file sharing for worksheets or homework. Everything has to be simple enough to guide learners in Grades 1-7.

If you already have these files—whether it is a WordPress/LMS stack, Moodle build, or a custom PHP/React solution—share a link or short video walkthrough so I can judge speed, UX, and feature depth. Once I confirm the demo meets the checklist above, I will purchase the full source plus any required plugins and installation instructions.
