Multiple custom plugins (Rust)

Good evening to all, I am a researcher of an experienced coder for us creates several plugging as RTG UKN.
We have already created the map makes the arena delimited the area of ​​each arena ect all are in place we just miss:

For starters, on the hub (or players), I would like to have a portal (in a place that I already built), which teleports us to different places. For example, to access AimTrain, it is necessary to execute the command "/ at". Except that I would like that when we enter the portal, it executes the command "/ at". For the arena, we enter a portal, for example "arena 1", which teleports us in a room of choice if we wish to be part of the team 1, the team 2 or the spectators, then that we tp in an arena that I have already done, with a predefined kit. by spanking / r, this puts the player ready, and a GUI button that incorporates: arena kit change, the first one that joins the arena is the "owner" of the arena, this is the one who will launch, ban, whitelist, forcestart, start and change kit. There will be a team A against team B. Once all the players of the opposing team are dead, the game ends. And to replay, you must enter the com / r. Players will have walls in their kit that they can use for pvp. At the end of the match, the walls are automatically removed. So that the next part is clean If you want more information or if you have a doubt, contact me via mp or via discord Empire.IceLab # 6821
