build a website

Need an Website with following features: a) Register using email id b) Option to add payment details, Credit/Debit card or online wallet c) Website should provide a chat option. User should be able to chat with the customer service executive d) User should be able to call using the Website. (please note that the Website should have a calling feature using which the user should be able to make a voice call to the customer service number) e) User should be able to view profiles on Website and should be able to schedule an appointment with one of them. (He should be able to see the profiles of all performers and should be able to schedule an appointment) f) If a user tries to schedule an appointment, he should be charged appropriately on his card or wallet. Also block the calendar of the performer. g) If a user schedules an appointment, he should receive notifications on Website and reminders on his email, 15 minutes prior to the appointment time. h) At the time of the appointment. The user should have a provision to make a Video call to the performer. (If the call goes beyond the scheduled time, we should be able to charge the user for the extra time.) On the other hand, a) we need a portal where in customer service executives can respond to user chats. b) All voice calls from Website should be routed to the customer service executives phones. c) Performers whose appointments have been booked by users should receive notifications 15 minutes before the scheduled time. Also, they should login to their accounts and attend video call that has been initiated by the user. Non Functional Requirements: Simple User Interface. Simple design. Better if we can use any open source tools for any of the features. Note: Mentioned above are the technical requirements for a "Adult Cam App/Website" Also, we need an Android App developed with the same requirements as that of Website. Please note we are looking for a team that can work on Design and Development. Those who can do only design/development please excuse.
