Work Performed: Offsite Project Description: need site (prefer WP) to sell new book (with my affilaite links) on amazon & B&N. both hardcopy & nook/kindle versions. book cover already designed. book is an autobiography. authour featured on news. ideally, (but not a must): -help in promotion of site & book. -optimise site for SEO (with wp plugins). i will provide keywords. I'm open to proposals on design & promotion. if happy, will order additional sites & work. Questions: 1. can you create a great looking Sales website and you prefer the promotion to be done separately or are you good at that as well ?? (either is ok). 2.
