Don't know of any Ebook or PLR.
But what are your plans with the ebook ?

If it is you personally that wants to learn how to make videos with your phone. Go here and watch this video on you tube - https://www.youtube.com/watch?v=7YLKcv69HQU

I fully support making an Investment in ones self but I do hope you aren't considering buying an ebook to teach you how to make videos on a phone .Search on youtube and google .You will find Tons of free content out there to get you started and going with the basics.

Thanks for the reply. I need an ebook for my purpose. I will be giving a free ebook to the person who fills out my contact form. I don't mind buying an ebook initially with PLR rights. You can get this type of ebooks for free or usually as much, I have found for $7.00 one time. When I get ebook on the subject that caters to my needs. I will check the information in the ebook with what is talk about in the YouTube video. If the information correlates with each other, I will use the ebook.
