Help With My Server!

I want my server to have Evo-City but i can’t find a descent caveblock. All the caveblocks on garrysmod.org are useless adv dupes. I want a good caveblock, does anyone know one? Thanks!

PS: I’ve heard of servers having one called death barrier but i can’t find it. can someone please help me find deathbarrier or atleast something equal!
