We need an illustrator for mobile interactive book

We are currently working on a mobile interactive book. So, the project is, on each page, there are some animals which the user can interact, for instance, make a giraffe move when you touch it. Each page has a text for the story. According to the style that we want, we are using real pictures of animals for backgrounds character. However, we would like someone to draw all main character for each page and eventually some movements that they can possibly do (Like make a lion running). We don't need so many drawings for each movement. For the style, for the moment, we would like something realistic. However, we are open to other style if it's good and suit the background, so as the story. We are currently working in Hong Kong. If possible, have a real meeting so that you can fully understand what we expect. If you would like more information, please don't hesitate.
