Warden System

Would some people mind giving me some help coding my Warden system? What this requires is that when the player is dead a sound plays, somebody can only be warden before 1 minute into the round, also need to replace ROUND X on Fretta hud with WARDEN <wardenname>. The warden system will work by a chat command /warden or a console command tz_warden. Also, the warden system needs to reset on round restart. If people can help me get started I would be really grateful, thanks!
