I need a plugin that has bounties and guns and jetpacks and houses and stuff like that. I know that is a lot to ask so you can make them separately and over a lot of time. There is a server that I have played and I am kind of taking the inspiration from that, this is the server: https://minecraftpocket-servers.com/server/55678/
Chances are close to zero that anyone will even try. You're requesting fully pledged game mode. Which you later will use to gain profit. Just sayin...
Use the official bedrock dedicated server and use behavior packs. Like Primus said, the chances of someone actually making something like that is very low.
