Build notification bar and add it to our website

I have a website and want to add a notification bar to it, i want it to work the way the notification bar works in this video - [login to view URL] Look from 19 seconds in the video, we want the same scroll text and movement up and down and left and right and the same speed. I have also added a screenshot to show where to look in the video and which notification from the video we want to add to our website, please see the '[login to view URL]' screenshot attached, i have put a black square around the bar. So we want the scrolling effects from the video exactly the same and the I want the 'i' icon on the left also. We have conditions for the notification bar and what text should appear i will send these in freelancer chat to you. The only thing that is not in the video that we want to add is a very small pixelated icon on right hand side, I have attached a sample of what it can look like and it should animate randomly. The animation of this pixelated icon could be 'smile', move face feature from left hand side of face to his right and lastly we can do some form of moving forward animation. See example for the pixel icon in screenshot - '[login to view URL]'. We do need a strong and robust solution to this work that can handle a high number of users on our website at once so about 1 million users so you need to decide which solution is best for this either node.js or ping solution or other? Please let us know. All of this work you will need to create and add it to our website so its fully working. I will tell you some of the information/conditions we want to appear in the notification bar over freelancer chat. If you have any questions please do ask.
