Messaging integration for ionic IOS app using Firebase

I have designs, a prototype and a user flow doc with clear design guidelines for chat functionality that I would like integrated into an already marked up and styled ionic application. Chat Requirements: - Inbox arranged most recent message first. - Ability to create new chat / new group chat. - Ability to add contacts to a one to one chat to create a new group chat. - Ability to clear conversations from inbox and from within message. - Ability to send automated message from an opportunities tab. - Create new message or Add to chat screen shows ALL previous connections regardless if chat has been cleared from Inbox. - Indicate timestamp in bottom of msg box. - Create screen for new chat opportunities with some aggregation logic. I have a 6 week timeframe and would like a version of the application online for testing
