Wordpress - Website Development

We are looking for an experienced Wordpress Developer to create a blog website and template that we can easily modify to use for other blogs in different markets in the future. We especially like the functionality and layout of: http://www.naturalnews.com. Of particular interest are the nav bars, search bars, advertising placement, page and post layout templates and monetization methods. The website should have superior onpage SEO, and be fast to load. It must support a number of plugins we will add at a later date for SEO, Social Marketing and other purposes. This is a high priority project with a short deadline. We will only entertain fixed price bids with specific completion dates. We will purchase any recommended themes or plugins ourselves.
