I need a minecraft server plugin developer

so, i need a custom minecraft parkour plugin. basically, you start in a spawn map (obviously) ,and in your hotbar you have a nether star. when you click the nether star, you get a gui. first row will have a coal block, lapiz block, quartz b lock, iron block, etc. all the way to netherite block (so this is 1.16). below each block there will be an ingot variant of that block - 1 in the second row, third row, and fourth row. ill explain later. then i need each one to teleport yopu into a level. i need a time tracking scoreboard, completion button, starting pressure plate, etc ill explain more later. use this minecraft server for inspiration: mc.parkourcraft.com. also i need the config to have a lot of customization options.
