Hi,
I see a lot of "copy paste" proposals on your project with a few keywords that have been changed, so I want to start out by saying that I am an individual and I don't just copy and paste bid proposals in mass quantities like a lot of people on here do. My work title on this platform is also more video based, but I love Minecraft and if I see something Minecraft related that seems cool I just have to bid on it haha.
Okay so. I have been running my own private server on and off for a few years now. In that time I have delved into plugins soo much that there are nights I even have dreams of writing out commands haha. I love setting up servers and adding custom features to the game more than actually playing and I love finding solutions to difficult problems in regards to gameplay and permissions especially. And "luckily" (see what I did there haha) I've been using Luckperms exclusively for all my permission needs since the beginning so I know it by heart. If you are willing we can discuss adding an additional plugin in order to even add an inventory/item based GUI in order to easily assign ranks to players each with their own unique set of permissions. Also my bid says 1 day, and I am sure I can get it done for you within a day but I don't mind spending more time helping you customize and setting up your server because I enjoy doing it.
An additional bonus is that English is my first language so communication should be a breeze.
Looking forward to your response :)
