I need a Minecraft developer. -- 2

I co-own a Minecraft server and we're just getting started with it. We're looking to have a "gen" server (In case you're unfamiliar; A generator server is where players will start out with an early-game generator, these generators will generate items which you can sell to a shop for money which you can use to either buy more/better generators, or upgrade your current ones.) We would need a plugin that would handle the shop and the generators.
