Kasie,
I live near Hollywood, California, where many of the movie scores are composed. It used to be that people would spend months slaving over hand-written scores. Next, they used composition software. The big thing now is the "one-man orchestra". The software and samples are so good that it allows someone without access to a performing orchestra to compose for, and create a finished product of, all the instruments.
But here's the catch: what I, and most others, want from orchestral scores, is for the emotion of the movie to be augmented; to give me a way to access the feelings that the director is trying to evoke.
That takes a strong understanding of orchestral instruments, tempo, dynamics, etc. No doubt your friend has software to do this, and it sounds like he has a good understanding, and passion for, this kind of music. But proper training is crucial.
If he really thinks he's ready, have your friend look to the local universities for film students that would like a score for their projects. Usually they'll have no budget, but he'll get a clip for his reel. With a few of these under his belt, he can send his reel (okay, CD-R), to managers/agents in Hollywood. (Or the film-making hub of whatever country he's in). There's a great directory that I've used to pitch music to music supervisors of movies - I have two songs under consideration right now, and have pitched others.
In summary, 1) You have to have a quality product first, or they'll write you off, because competition is fierce and plentiful; 2) You have to have a demo reel before you start pitching; 3) Don't give up in the face of rejection!
Hope this helps!
Claire
