Graphic Design West Midlands

I have just finished writing my first book. I"m going to have it published next month, and I have already found a publishing house which might accept it, but they say that I have to care for the visual part of the cover by myself. It"s a book about martial arts. It focuses on how they became popular in Europe and America. I guess I would rather not design the cover by myself. I know what it should look like, it"s already there in my head, but I"d like to have it created by an experienced graphic designer. There is a company in my town called Graphic Design West Midlands. A friend of mine once mentioned the name to me. It was perhaps a year and a half ago. I remember that she was looking for a good graphic designer to create a logo for her new business. She finally found an experienced specialist who worked for this company. Well, I turned on my computer yesterday to get some more information. It was not very difficult to find their website. iphone app development turned out to be just a small business, but their website looked promising. I liked the layout and the combination of colours. I wonder if they might use some traditional elements like kanji (Japanese characters) to design the cover of my book. I"m going to call them in a moment and ask!
