help please

I know this is probably a really easy script for you scripters...but I'm not a scripter, so I would appreciate any help

How do you script an npc to give you a prize if you touch it within a certain amount of time?

Example: lets say you have to hammer down a whole bunch of stakes in say 30 seconds, then touch the npc at the end, or even do a variety of stuff, like move rocks, bushes, hammer stakes, and so on....how do I get the npc person to give the prize if done in that 30 seconds?

Or even better....get a chest to open with the prize in it when touched within that time
