My old server finished, I never really put MAPS on and such..

So, I need to know how to do this thing. And where to get.

Good Zombie mod with inf ammo.
How to install models of zombies, and where to get.
How to sell admin to people but they bind @menu, then when they hit a key, it brings all that up.

Good cheap server, I'm looking for about 50-70p per slot.

Thanks.

Also, I may be giving out free admin, to a few good friends on here.
once my zombie server is up.
