Making a big map but need help i already have ideas for it

[Scott Snyder]

Im trying to make a map, i also dont have a name yet.

But i already got good ideas for it like when you spawn your in a big area with a pistol and a teleporter and the teleporter is already linked but you have to wait 30 seconds to use it while zombies are like they are round one then 5 seconds in the time they get health like they are on round 18 and dogs spawn too, thee is jug too and a gun on the ground u can pick up and i need help with the cool stuff like a music box a easter egg and a buyable ending

so if anyone can help add me on skype or pm me

skype= a7xforeve225

EDIT: the person is gonna start off in a colloseum and teleport to a big box for now
