Admin panel for application owner (that's me) Backend for user Payment gateway SMS API- want this to be integrated with sms api ... so it will act as a reminder....sms will be received by both the parties before 30 mins who are set for the appointment Email reminder I know similar product in market one of them is [login to view URL] I want you to sign up here [login to view URL] and see the features.... web presentation, calendar look, user backend. In addition to all the feature I would also need banner and ads management in site as backend. I have also attached screenshot of the webpage so you know how it should llook.
