Build a website/community with videocalls similar Mytutor.co.uk or Italki.com

We would like to hire an expert developer in order to build a website with a quite similar structure as [login to view URL] or italki.com. The aim of the website will be a "market place" for doctors/health specialists to offer their services and the possibility to have videocalls with their patients. From the patient side, they will be able to complete a private profile to be share with doctors once they match. they will be also able to search for professionals filtering by variables like speciality, rating, price per hour, etc. Example: [login to view URL] Doctors will have a public profile where they will be able to promote themselves with their CV, videos, their rating score, reviews from users, etc. They will be also able to set their tariffs and share their calendars in order to let the users know their availability, so some schedule/calendar plugin will be needed to match supply and demand. Last, once the match is done, both doctor and user will have a personal space where they will be able to have a video call or chat. Doctors will receive all the private user information before the call. Please, visit both sites to have a better understanding of the platform needs.
