I need someone to assist me in creating ePub versions of my music tutor books suitable for viewing in Apple iBooks, Google Play and on a Kindle Fire. There is a small amount of text to be formatted but the majority of the pages will be sheet music. I will need to embed audio and video throughout the publication. I have sketches of the layout I desire and a rough design for the cover but I need someone with a strong background in graphic design and book layout to help turn the book into an engaging product. Work will be initially for one book (approximately 40 pages) but eventually there will be six books in the series. The book must be compatible across the three platforms I have mentioned so you would need to be experienced in submitting ePubs to these.
