Mobile development

I need an iPhone/iPad app. I would like it designed and built. The project is a to create a audio for a book. This book is over 400 pages. The book teaches Arabic to non-Arabic speaks. I would like the words to be highlighted as its being read with the audio and also have a repeat button so you can listen to a lesson as many times as you want. The book also has many exercises that have to be done by the student and the app would show the student if the answers are correct or false. The book is in arabic so you would have to understand arabic. I already HAVE THE BOOK IN PDF FORMAT and AUDIOFILES To go with it.
