You can either rent a server for really cheap from
www.elitegameservers.net - where I can help you set your server up.
OR
There's other ways you can host.
a) Download Hamachi, connect to each other, set up a LAN game.
b) Try to set up an internet game, although this can be quite hard. You have to check, disable and enable a few settings in your firewall and other settings within your security program to get it working fully.
Hope this helps (:!
