I need some Graphic Design

We are producing a three volume English textbook that will mainly to be distributed through Kindle and the iBook store. We need a professional cover page design for the textbook. Each of the three volumes will have the same design with a slight color variation. We are looking for a clean, simplistic, modern design mainly using pale orange, blue and white. The cover should contain the title, volume number, company name/logo and author name. See the attachment for a sample of the inside of the book. Please provide one sample cover.
