Naughty, unfortunately if a person wants to be a model they have to pay for portfolio pictures. There are so many wannabes in California that agents have taken to charging for their services first (much like publishing). However, a real scout hot for your friend would do free test shoots for his/her bosses before continuing.
Now, if your friend likes the idea of being paid for appearances and wants to break into the game cheap then a stint as an extra is an excellent way to start.
CENEX Non-Union Extras is where most locals get their start. I was with them for nearly a year before I decided to concentrate on my academic career. I had more than a few job matches but school always got in the way. And, no, I'm not pretty - extra work is based on your size and gender.
