Build me a live chat web app with simple post API

I need a live chat web application for employees to talk to customers. It will be able to allow multiple employee operators to be logged in at once. To be built with PHP + MySQL + AJAX + JQUERY + BOOTSTRAP if internet disconnects, it should check to make sure any messages come in properly no errors or missed messages. ** Features include ** - multiple employees logged in - departments (category by employee type: billing/sales) - transfer chat to another agent/department - mark chat as ended or how it ended - small order form on livechat end - order form will use stripe to send a pay request form - more small to be added Developer should know how to work with STRIPE api, as their will be a function to send a pay request and take orders. needs to be completed very quickly please type 'aliens' to confirm you read this. i prefer to work with 1 person developer who can dedicate time aside for this only to get it done quickly.
