We are planning a series of books. What we are looking for is a book cover design that will act as the base template for that series. We'd like the general design concept to incorporate the ideas of volleyball, coaching, and excellence.
Please note that these will not be technical type books. They will NOT feature drills or games or anything like that. Their focus will very much be on coaching philosophy.
Each book in the series will have a title that starts "Volleyball Coaching Wizards" with some kind of extension from there. For example, "Volleyball Coaching Wizards - High School Greats", or "Volleyball Coaching Wizards on Developing the Team Concept". So the design will need to allow for addition of the title extension, as well as for inserting a separate subtitle, and also author name(s).
In order to show what a complete book cover design would look like, feel free to use one of the title extensions above. Similarly, you can make up a subtitle or just use "Insights and Experience from Some of the World's Great Coaches".
