[PURITYPRISON CODING HELP] GET REWARD IF DONE!!!!!!

So for my prison server i want to do something different i want my players to rankup from breaking a certain amount of blocks and display next to their name

V
A-Prisoner: default
B-Prisoner: 2500
C-Prisoner 5000
etc multiplying by 2 then once they get to free they start paying with money (prestige plugin)
If someone can code the plugins (prestige plugin + block rankup also doesnt have to be the same person) like that will get the highest donor rank or maybe staff rank in my server!
Just say in the comments your Skype and add me: Fantersterc
