Convert and existing messaging template

The project is about developing a very basic messaging system for a webapp, a much simpler version of Tinder's. This is an exercise in order to find the right person to hire full time once business goes live. For confidentiality, work has to be done through TeamViewer on a remote computer. If this condition cannot be met, please refrain from bidding. Some experience with ajax is necessary, and will be closely connected to html/css/php/mysql that have already been implemented. The webapp template is bootstrap 3. The messaging system needs to be tested as well. The main tasks: - very basic version of Tinder's messaging system only (to be discussed in details if necessary). No photo or file uploads, just plain simple one-to-one messaging between each pair of matched users. - Has to be responsive. - when page is accessed by a user, php file will query mysql to see which matches user is able to communicate with, and will contain a log of each message thread (see attached picture). - ajax implementation for live replies Please contact me if you have further questions. I can guide you through the code if needed. Once this task is successful, more work related to other parts of the webapp will be discussed in a separate project. I will NOT consider bids which description is a copy paste. I need a response to what I wrote here SPECIFICALLY, and MOST of ALL the library that you would plan on using (nodejs, etc...) If you do not develop a serious bid, please do not waste your time, nor mine. Also will NOT consider bids above $100, as this is not a running business yet. If you do a good job, you will be the first to be asked to join the nucleus team. Thanks!
