[L4D2]New Plugin Request-Store with activating code system

I am currently working with my own server of all mode. And I am searching for a plugin that people can purchase things in store by using the game-points given due to winning a game and killing infected.
Also, I want to add a activating code system in this plugin; Therefore people can get given amount of game-points by entering activating code randomly generated by the system such as XXXXX-XXXXX-XXXXX-XXXXX-XXXXX , XXXX-XXXX-XXXX and XXX-XXX-XXX

Cheer~
