Even so, most people go into game server hosting thinking there can't be much to it only to go out of business six months down the road. Places such as Insomnia365 (ThePlanet) will only cater to these problems to a certain degree and have a totally different set of priorities than you do.
I mean, if all there was to operating any form of server hosting business was taking people's money and rerenting others' hardware, then I imagine a lot more people would be making a lot of money - rather than going out of business.
Here is the thread regarding this at The Planet. Read the whole of it. If you don't have time to read all six pages, you certainly don't have time to operate a GSP.
