Help me make an illustration for the chapters in my book, The Restaurant Marketing Expert!

The Restaurant Marketing Expert

The target audience is people in the restaurant industry. These are people that either want to open a new restaurant in the next few months or in the next year, or they already own a restaurant and want to increase sales and deliver better service. It's for my upcoming book titles: Restaurant Marketing: The Secret is in the Sauce®

For this contest, I am looking for 4 illustrations that will represent some of the chapters of my book. There will be 30 illustrations total, and I'd like to work with the winning designer of this contest in a 1-to-1 project to get the remaining 26 created.

These illustrations can be simple and don't have to be extra unique or detailed, but I am going for whatever looks sharp, and whatever can help my book stand out and look professional. They should be black and white.

I am self-publishing but I want my book to be able to compete with the best of what's out there.

Please make 4 illustrations based on the sample chapters below. I will choose the winner based on what I determine to be the look I am going for in the book. The images will later be transferred into my book and will be featured at the start of each chapter.

For an idea on how to do the first illustration, please read our story at http://zankouchicken.com/timeline/. Here are the sample chapters:

1) The Story of Zankou (storybook elements)
2) Hollywood in 1984 (how we opened our first store)
3) The Yin and Yang of Yelp (this chapter discusses all things Yelp)
4) the 12 Styles of Leadership (this described different leadership styles within the restaurant business.

I am also including what might be the photo that will go on my book cover.
