I need an e-book designed

I have written an e-book and i need it designed into an attractive pdf which works with my branding. Please see www.zappcommunications.co.uk for further info.

I believe that landscape is the best format for ebooks.

It needs to be eye-catching and will have to have some diagrams and charts to make it stand out. Branding is very important so I really need someone who has proven experience in creating ebooks. Please share examples.
