Minecraft survival server (already have hosting)

Hello I’m looking for a designer for a Minecraft server that I recently bought. The main goal of the server is to have a survival treasure map theme going. There should be spots that take tremendous finding to get too. Also if somebody finds one spot it needs to not reappear in the same spot again. Throughout a whole Minecraft server I’m thinking about 200 chests. Some will have valuables in them and others will have very few valuables. So the point is to survive and to mine to find the treasure to help you survive even longer. It’s team based. So teams can kill other teams as well. Thank you.
