Book cover design

Information for the business: We inspire people to turn their dreams into reality
Industry: Business
Design details: I'm currently writing a self-help book on developing self-confidence, and I'm looking for someone to design 3 book covers. The book will be published as a kindle e-book and a paperback (A5 size). The kindle e-book will be published in two parts (part 1 is looking at the issues surrounding lack of self-confidence and part 2 is about setting goals and achieving confidence). The paperback version will have parts 1 and 2 in the same book.
My book is designed to be a coaching programme in a book. Not everyone can afford to pay for life-coaching support to achieve their desired level of self-confidence, hence a book that will help them achieve the same result.
I don't have a design in mind yet so would welcome any suggestions. I'm open to any colour scheme apart from orange as I really don't like the colour orange
I'm looking for something that is eye catching but not loud and ugly (you only need to look at books on Amazon to understand what I mean).
I'm looking for the task to be completed by the end of June at the latest.
Target audience: Adults
Ideas for the visual style: I'm open to suggestions
Where the design will be used: Book cover and my website
