Create a Messaging System for my new Website -- 2

I require someone to create a messaging system between users and companies on my new directory website. The website is being constructed in Phalcon, PHP, Nginx & MongoDB so experience with these are essential. If you do not have experience with Phalcon do not apply. The messaging system will need to operate similar to LinkedIn & Freelancer. A user will be able to message a company through our website. The company would then receive an email notification saying they have a new message with a link to read the message on our website (once they have logged in).
