I have more than 10 years of experience in graphic design, having developed special skills in book design. Besides converting your files, I can ensure they remain well designed, and that you will be able to edit them. I have provided several customers with this kind of service, where I set up a file to be easily used.
You can check some of my work in my portfolio, which includes several books.
