Can I hack it?

I am an 2nd Assistant manager for discount retail store with 6000+ locations. I would like to work at the ';home office'; in LP (loss prevention) or possibly the display store. What is required in these fields? I have nothing but experience backing me since my ';some college'; is in psychology. I am a good, and flexible worker. I work hard at what I do and consistantly surprise my boss at my ablility to get things done in little amount of time. I also have a knack for making things ';look appealing'; so I'm thinking the display store where we set things up and take pictures for the company to send to all of our stores and show them how it's supposed to look. Or in LP I know many things about company theft since I have the kinda face that ppl will tell everything too. Just gotta get over that fear of being a narc. What do you think? And what is needed in these feilds?
