Chapter art for non-fiction novel

Hello, I am looking for an artist who can do some sort of black and white /sketch art / photos that accents my chapter titles. I have 43 chapters in my book. A few sample titles are: A Beautiful Parasol, The Meeting, The Party, First Contact, A Piano Lesson... I want something simple yet elegant. The images can be converted photos or freehand drawings. I can send examples of what I am looking for but everything I have is just stock images found on the web that I have converted with Photoshop to line art. I want this book to be completely original. Thank you for your time. Jes
