New posts/pages for existing website

I am looking for some new pages to be designed for my existing website. The product I am promoting as an affiliate has a new range of individual items that I would like to promote. There are approximately 20 products to promote. I am looking to discuss the best way of promoting these new products, for example, multiple pages/posts, all items on one sales page etc These new pages/posts will be then promoted using several SEO techniques (not part of this project) The website is built in Wordpress and is a few years old, already attracting sales on other similar products Required: - advice on optimum structure for new range of products - advice on SEO for new pages (and rest of site if appropriate) - copywrite new sales pages - build new pages in Wordpress - offer rewrites and tweaks if required Please ask if I have missed anything out
