What is the process for hiring and working with a DP for film?

I’m working on a short film and I’d like to hire a Director or Photography to be in charge of lighting and camera work. I’ve never hired a DP or worked with one and I am just unsure of the whole process. I don’t want to be unprepared when I meet with him. What should I have for him when I meet with him? Do I just simply tell him about my movie, and show some examples of the lighting style that I want and then let him do the rest? If anyone could give me a simple “walk-through” of the process It would help me a lot. Thanks!
