Online Tutoring Marketplace

I'm looking to establish an online tutor marketplace analogous to italki.com and preply.com, utilizing features similar to what offered by pinlearn.com. We need three types of user accounts: students, tutors, and admins. The features for each are:

For Students (as a minimum):
- Ability to search and filter tutors
- Capability to book one-on-one and group tutoring sessions
- Possibility to leave reviews and ratings
- Sign up for subscriptions
- Integration with Bigbluebutton tool
- Payment options through Stripe Connect, Google and Apple Pay, among other methods
- Calendar synchronization with Google and Apple.

For Tutors (as a minimum):
- Functionality to create and manage profiles
- Ability to set availability and schedule
- Receive tutoring session bookings
- Opt in for subscription for repeated lessons.

For Admin (as minimum):
-Dashboard
-payout

Ideal freelancers for this project will be proficient in not only the development of digital marketplaces but also in integrating third-party tools such as Bigbluebutton, Stripe Connect, and Google/Apple API's for payment and calendaring functions.

The project will be: Website + Android App+ IOS App.
