The popular webcomic Penny Arcade holds a gaming convention every year called PAX (http://www.pennyarcadeexpo.com/). Their tournament organizer has stated they will most likely have a L4D tournament this year. Myself and two others are looking for a solid 4th player who will be attending PAX (first weekend of Sept in Seattle) to fill out our team. We hope to scrim from now until the tournament.

Please add me on steam if you're at all interested: http://steamcommunity.com/id/vindexus
