As soon as possible

I need a short 1 minute video trailer created for my new book. I can send you examples of what the video trailers look like with the publisher to give you an idea. It mainly consists of words on the screen and music.

I have a copy of the front/back book cover, but I do not have a copy of the actual book itself which is what you may need. Can you tell me what you need to get started and roughly how long does a project like this take?
