Brand Identity for Product

I am developing a journal for people who are preparing for a professional exam. This will be the first of many other products tailored for a specific profession. I am looking for someone to help develop the brand identity which should include, colors, logo, a mock-up of what the product might look like and how to position it in the market. Once I select the person, I will share a document with references that I have put together so that you have a better sense of what direction I am hoping to go in.
