Ender Dragon egg and prize for killing the dragon

Please could someone make a plugin so when someone kills the enderdragon, the eggs goes straight into their inventory and they get a prize of 3-5 diamonds. Please include that the end resets every 4 hours. Thank you

EDIT:
Suggested name: Resetting End

What I want: A plugin which will make the end reset every 4 hours. There could be a command which will reset the end hhowever long it's been since it last reset. Please have it so the person who kills the dragon has the egg go straight into their inventory and they get a prize of 3-5 diamonds.

I use group manager just so you know, I'm not sure if it matters though

Ideas for commands: /resetend

Ideas for permissions: endreset.allow

When I'd like it by: Sometime in the next week would be helpful.
