VPS Server Management Configuration / Programming Job

We need a system integrated into our site that lets users pause and suspend their VPS along with being able to see the status of theyre VPS (Paused or Suspended). It would need to send commands outbound via SSH to servers. The billing system we use is WHMCS. Each user has an account area that is populated by a PHP template ([login to view URL]). I have attached a screenshot of the client area and your account appears to still be enable for access so you should be able to login and access your old clientarea. I would like a status indicator (red or green orb) that pings the server and returns the status as green for up or red for down with the work Up or Down next to the button. If possible I would like this indicator refresh itself every 15 seconds Below that I would like a button to Stop the VPS. SSH to the customers node( a variable in the billing system) once SSH is established it then uses the "nvrun" command to issue a stop command on the VPS with the clientsname+clientnumber. It would then need to pop up a small box advising that it successfully shut it down or if for some reason SSH could not be completed (IE the node is down or the command was not successful) it would need to return a failure. As far as the start button goes it would be exactly the same except it would issue a start command to nvrun. Currently we have about 15 servers running, I would want the servers to only accept SSH connections from my main server. If you have any better idea than using SSH I would be open to your interpretation. The functions just need to be able to execute commands on each server. It would be possible for me to setup test instances for this connected to test servers.
