Blog Illustrations Required

We are a small consultancy company that helps businesses get more from technology. We are in the process of overhauling our website including a blog, and require original illustrations for some of our blog posts.

We will provide direction, for example one of our posts is about Linux & Open Source and Business, and hence we would require a penguin (Linux mascot) in a business suit looking smart. Please provide example works or portfolio and cost per illustration.
