Scripter needed

[Ivy Riverview]

I'm holding a contest and I need a script system that will allow me to have specific items given to three separate people, but I need it so that they can only access the items in the ones meant for each of them, not for the other two. So items for #1 only #1 can get, not #2 or #3 and so on. I'd also like it if the script would work across multiple owners on more of a server type thing if possible that way I can edit it without all of the others having to come in and replace the script. Or something like this. I need it before the end of October.
