Site translations + SEO

We require a website translating into various languages, including but not limited to, German, French, Italian with the possibility of more to come in the future. The caveat to this is that we do NOT just require a straight translation, we would need the entire site to be translated with SEO in mind - eg, you have to fully understand what you are translating, and word it in order to capture phrases that people would be searching for in relation to our site. This means that both fluent English and the language you would like to translate into are essential, as well as strong SEO skills. We will expect to see examples of previous work.
