Target Practice MiniGame

Suggested name: TargetPractice

First off, i HAVE looked for a few days and cannot find anything that i need. What i need is We have a castle type factions spawn. In the back we have like scare crows that we have set up to shoot at with bows and arrows. So i would like to integrate where They get like 1$ each time they hit the middle block. So at the closest fence if you hit it you would get 1$, the next farthest one you get 2$ and the farthest one is 5$. And i would need it to go along with the eco system. The people on the server can use money to buy things for factions.

Ideas for commands: Set prize, possible change range,

Ideas for permissions: Im not sure with Permissions

When I'd like it by: by next month would be great!
