I am looking to enhance a chat app to filter the operator(doctors) and introduce pay per session. following is the list of task.
1. Add details to doctors' profile like country, specialization tags, trainee/GP/Specialist/superspecilist, rating. display it in user chat window
2. Show popup only after click. filter which operator who will receive the request
3. Allow only one window allowed. prompt to close session before he/she chooses next customer. Close session option for doctor and acceptance for patient. add rating after user accept the session end. prompt user when window is closed
4. Pay in advance through paypal. record the transaction in admin.
best of luck
