I'm curious about this as well. I've been thinking about putting together some samples. As a musician (a fair number of us here are actually), I can do original music as well as the production. But I'm not sure about the demand or what a reasonable price would be.
I wondered what writers did for music, because I wouldn't think you could use anything without permission. Nice thing about original scores is they can work directly with the idea of the video. I hope you get some responses here. Good luck.
There are lots of sites that sell music loops - like stock images. In fact, some of the standard stock image sites sell them too. Here's a couple: (They cost anywhere from around $10 to $200, and some are completely free too - for around 30 secs - 3 mins of music)...
And I just saw this post over in the Book Bazaar! It's someone who just completed his own book trailer: http://www.kboards.com/index.php/topic,136824.0.html
Oh, and on pricing of trailers - when I did my research I found the prices to be from $300 and up for the making of a trailer, also depending on the length...some companies go up to $2000 and many charge $500, but with the footage costs excluded...so I set my own price at $300 a trailer, footage excluded...it also depends how much input the author gives. If the author wants you to read the book and write the script too, that's a LOT of extra work, but if the author has some basic ideas and script already written, it makes it easier, though best is still to read the book and get the mood...
