Time for a Book Trailer

My plan for tomorrow is to get some serious work done on a book trailer.  I am going to be posting/requesting any information or tips anyone may have for me through the kindle boards.  You may also post here if you want.  I think it will be a fun thing to do to bring some attention to my book before I reveal the cover.  So, if you know anything about making a book trailer or can refer me to anyone please do.
