A nice idea icewind

Let's begin simply and here is my idea :
- Name : Treasure hunt.
- What is needed : tons of items. About 10-15 different type of items, going from a simple chocolate cake to revolver.
How many players : from 4 up to 10-12
How long will it take : Depends on how hard and how much items you hide. I would say : 1h or maybe more
-Short explanation : 2 players hide some treasure ( items ). The other must find them by teaming up or playing alone. There would be some kind of " level " to found items like :
Easy : full battefy pack, chocolate cake, every type of ammo. ( except RPG round that cost a lot )
Medium : stunstick/crowbar, pistol, lottery ticket XXL.
Hard : Shotgun, smg, revolver.
and finally the treasure : cuffsaw(15)
If anyone got suggestion abouts price, number of players etc... Tell me

Main problem of this event : The price of the items you must hide. It would cost a lot but if many people give for example 1 revolver or 10 stunstic. Then we will be able to do it !
