Hey there,
I have three years of Java experience and 2 years of experience with the Spigot API (if that's not what you're using, that isn't a problem- I'm familiar with just about everything out there). I'll be able to get this done quickly and effectively and provide technical support in the near future if it is needed.
Whether you need this to be a custom plugin or a tweaked version of an existing one, this won't be too hard.
Looking forward to hearing from you!
