Integrate Chat And Message System To My Website

I recently created a website that you can see below [login to view URL], in this website users can enroll and sand message to the admin, because website basicaly was created for a marriage agency. Nao we like to change and doing a chat message website, where the people can chat each other, and sand file and smile, when the users are offline, we like that they recive the messages in theyr email. In the chat and message system, girls and woman can sand the message for free to man, man also can sand message for free, but we are going to add a limit for example a message any 10 minutes, than when they upgrade the profile, they are free to sand as many messages they like. In add to chat system we need to add a payment system and some futures like add to favorite, last person that see my profile etc.
