Clever fun book cover needed

The 500 Calorie Solution

We are a small company that has just recently spun out of a larger group. We publish products in the weight loss & fitness niche, both our own and the individuals we publish. It's an exciting time in out business as we just brought another huge person in our industry. The #1 reason was because they wanted to be a part of the innovative business we have. The number 1 things for us though is to work hard, have fun and make the weight loss experience fun and successful for our clients.

60/40 Women to Men; general diet demographic with
an emphasis on the lighter side of dieting.

We're looking for a book cover loosely based on the sketch attached. The name of the book is "The 500 Calorie Solution".

The subtext is:

No Dieting.
No Exercise.
15 Minutes.

Below that in a call-out of some kind:

Clever ways to burn 500 calories every day!

NOTE: There's an arrow call-out between "burn" and "500" that says "at least".

The top of the book is in a color bar:

The Smart Way To Lose Weight!

The bottom of the book will be the authors' names:

Jon Benson • Nathan Hopkins • Kelli Jennings, R.D.

As for the style:

We are looking for clever and fun. The artwork to be created is a scale with a light bulb on it, denoting clever weight loss.

The feel of the art and book cover in general is SIMILAR, but not exact, to the samples shown.

NOTE: Please do NOT use clip art or create an overly cartoonish feel. This has to be witty and original!

SIZE: 8.5x11 with spine; spine is about .5". We will also require and 8x10 version. Bleeds are fine.
