Competition mode request

With the rise of esports, me and a friend are hosting the first international Ace of Spades league. We would like a new game mode for this competition and maybe others in the future called competition mode but both of us are brand new to python scripting. I was wondering if anyone could either script this for us or give us help on how to script it. The gamemode would be like free for all but you can’t spawn near anyone else on the map. The other difference is that the game would be started manually by admin using a command. Thanks in advance for any help.
