Prison-zone [Help REQ]

Hello , Planetminecraft visitors
my name is Dennis aka Kijkuitman.
so , a couple of days ago me and my friend started to start our own prision server, so far we've done

[x] C-Prison a B-Prison a A-Prison and a Free-spawn

Todo
[ ] protecting A and free
[ ] Creating a Elite prison
[ ] Testing the whole server

i was hoping if some of you guys could help me out with the server cause i need some people to test it.
i also have a Question about Minereset
how do you add a warning
like; The mines will reset in less then 30 secondes

Thanks for reading guys
