Many authors find trying to make their own book trailer a daunting task. It does not have to be so…it can actually be addicting once you get started. Many professional sites want between $200 and thousands of dollars for these…with varying degrees of quality in my opinion. I have personally seen some trailers by amateurs far surpass some of those produced by professional sites. The total cost of the trailer should be around 30 dollars. Less if you have great pictures you can use.
