Minercaft server plugin

Hello I'm creating a minecraft server project for underground streamers, something like smp but with a hint of competition. I have a vision for a plugin that is based on creating clans, taking over areas, something in the medieval style Plugin must contain -the ability to create clans using a block from a special recipe -the ability to create outposts that expand the clan area also with the help of a special block -the ability to take over outposts -a special map showing the current territories for individual clans without a specific location of the block -tab with number of deaths and special colored ranks for members of particular clans something like essentialsx -I also need voice chat in the game -alarm for clan members in the territory if someone enters the territory without prior permission -the ability to defend the attacked outpost because the takeover of the outpost is going to take place for a certain time and a few players from the opposing team the possibility of banning on ip and general administration of the server -creating account passwords -welcome message -create a cuboid only on spawn -generating a special structure for the core of the clan building where the block will be and generating a tower-like outpost with a special block on top -barriers limiting the span of the world -the ability to exchange resources and the ability to create shops I need it done by the 27th
