The best way for us to get our own servers for Left 4 Dead will to raise the last $500 USD we need to purchase dedicated server hardware and run multiple L4D servers on a dedicated box (along with servers for games like Team Fortress 2 and Call of Duty 4). We've already raised over $1500 USD, so we're 3/4 of the way there.
