Custom prison rankup plugin help?

Hello, so i need some help on coding a custom plugin that lets users do /rankup and then promotes them to the elevated rank, but i want the plugin to support scoreboard, so it tells them how much it costs to rankup to the next level, and what level they are at currently.

Now I know that there is already a plugin like this out there but that is too much messing around and does not have some of the features that i want it to have.

If you can help please comment down below.

Thanks in advance.

What have you tried? Show us some code.
Hint: You'll need to use vault for this.

 

What is cult, and i havent tried anything yet, i want someone to help me build it.

 

@BaxterCoding Always better to tahg or quote them so they see your message.

@BaxterCoding meant to say 'vault' sorry that was a typo when I was on my phone.
