I am looking for someone to design an A5 flyer and business card.

I require a design for a double-sided A5 flyer. I have made a mock up, which you can see attached to this post. As you can see, I want something vibrant and eye-catching. This will be printed on high quality card. The reverse will be very simple, mainly text on a background based on the front of the flyer.
As much as I've made the mock up (and also attached the book cover from which i took my initial inspiration), I am happy to consider suggestions from the right person.
I am also looking for a business card design, which will be based on the flyer design.
