dear sir.
The trend in the future is that the final user of a book will read on an electronic device. So is wise to be ready for that trend. It requires basic html knowledge, photo-editing not necessarily advanced, and also knowledge of video editing. Is not necessary to be professional, but surely be a beginner is not enough. I' long time user of computers with all-round knowledge. We can try with a sample? I'm able to provide (at least in the beginning) good quality royalty free materials.
