The book I have written is called Appreneur - Secrets to Success in the App Store.
The book is the first of its kind in the sense that it is all about how to make your app a success. There are tons of developers stories and secrets that have never been shared before this.
The book is backed by some major companies so I need a killer cover.
One idea I like is having an iPhone like phone (cant be the iphone, but something very similar or a slightly modified iphone is fine) with icons coming out of the screen. The icons will be the icons from the apps the developers that are in the book have created.
I am open to any other idea or design, it just needs to look very professional.
Our website's color scheme is green black and grey.
It doesnt have to be these colors but brand recognition is always nice.
Cant wait to see some of your designs!
I have attached a sample I found on google, this should give you a decent starting idea.
