LOL! Just LOL!
If ever, anyone would in the right mind think of paying to be a GM on a server, would be if the member offering the deal is a staff member here on MaxCheaters for a trusting and reliability purposes. He would have to have a dedicated machine, domain, a name for his server, lots of people, a lot of experience and good/positive things going around about him. It would be a professional server with a lot of back story and information, and then maybe someone would consider your deal. Until those circumstances have not been met, you're sh*t out of luck.
