Realistically there's no generic way to just do this, since some private developer wrote the server software. I've emailed the production company to see if they specifically have any sort of external API that the server responds to, or if the only option is within their game engine. Assuming they do have an external API that the server responds to, like Counter Strike servers, Battle Field servers, etc, then I'm fairly confident I could code up an external program and/or a web interface to manage your servers. The product might even have some resale potential just looking at people possibly interested in a similar product. But like I said, if the developer says "No, we don't have any external API and won't be providing one" then it's possible I could decipher how their game code interacts with their servers, emulate it, and allow you to interface with the server, but that's realistically going to skyrocket the price way past your range.
