I make you a small simple bukkit plugin for Minecraft. Something like custom items that do cool things, or build-able machines that so stuff, anything fairly small. I will give you the plugin and I will not post it for anyone else. This is only for Bukkit/Spigot Minecraft servers, not Forge or any other game. If you the plugin to interact/change another plugin you will need to order a complexity add-on, change the gig count, or ask for a custom offer.
Make sure you message me before buying so I can tell you the price.
Also plugin prices may vary, they will not always fall under the add-on stated prices.
