I have a customer who wants to resell Web Hosting and Game Servers. I know this can be more money for me. But i am not sure how i should go ahead set this up or what could/should i do?

First of all, I suggest you do some research here on WHT to see what's involved in taking on clients who resell. If you have a control panel on your servers (Plesk, CPanel, HSphere, Ensim), you can add resellers fairly easily, but there is more work involved for you. I'd start by reading the forums.. I'll set someone else with more experience with game servers get into that one.

Good luck.
