Left 4 Dead 2 Sever?

[banditpaw1]

I would like to run a L4D2 so I can put some mods directly on it to share with. Just a convince thing. Anyways I've tried to use guides from the internet but so far it never works. Can anyone help me out? Perhaps set up a very basic one and upload it tforme to download?

Any help would be great,
Thanks.
