Asking someone to develop a script for you isn't the justification for "screaming" in the topic title as well as writing your whole text in bold. When you create any topic, please choose MEANINGFUL topic titles.
However... Regarding your question: I don't think, that this is completely a Sinusbot script. I'm not aware that JavaScript can dynamically create images to set this as the TeamSpeak server banner. The scripts engine isn't that powerful (yet). This may be a combination out of any Sinusbot script for retrieving the user count and a other part for creating the image. I don't know how the guy developed it, there are many different ways to achieve something like that. I would create it using PHP and the TeamSpeak PHP library to get the server data, create the image and set the image on the TeamSpeak server.
