Write some Software with a custom dashboard

Hi We need an expert PHP/javascript programmer to create us an alpha version of a popup script we need done. This all needs to be managed in a simple easy to use dashboard. We should also be able to lock it down with username and password and also be able to make more logins if needed. This script must be able to read real time traffic, generate a popup to tell one how many visitors are currently on the site or have made a purchase (fired off by a cookie on a specific page) and the user must be able to custom the look and feel of this popup. Once the popup has been created, the script will output a javascript for the user to add any given website and then the popup will execute based on the customization a user has given it. I also attached a picture example to kind of show the final outcome of what we are looking for.. This is just an ALPHA version and once this is working we will hire you for next phase of advanced development. Please only apply if you can start immediately Thanks!
