Redesign web page with SEO in mind

We want to redesign very simple static web page consisting of 4 languages and 10 pages per language (currently) in order to improve its aspect (we already have an idea of what we want but need further proposals) and put about 4/5 new pages (x 4 languages), as well as change some of the pictures which appear on it. Another important objective of this redesign is to optimise the site for top results in search engines for our key words (twist wrap, and 5 more words to be determined along with seller). Those web designers who do not have a good knowledge about SEO, please do not quote at all. We will need an invoice and all the code at the end of the job. If you need to quote higher than the price range specified here, please do so. Those sellers who do not have at least 8 ratings, please so not quote at all. If somebody wants to check actual web page to get an idea, please pm me & I will give you the url.
