I have found the content extremely helpful. It is very professional and informational, which opens up many ideas from my mind.
I wanted to add audio files to the E-book and all I had to do was provide the audio files and the job was done. The end product speaks for it self. I get good feed back from clients.
I recommend it to anyone who wants a professional end product. This was my first E-book and I will be doing more in the near future.
