Translate Website From English (UK) to German (DE)

We require someone to translate our website content (https://www.kitbuildings.com) from English (UK) to German (DE). It is very important that the freelancer who bids for this project is an English national with excellent German written skills, or a German national who has excellent English written skills. We do not want someone to run the text through Google Translate because this is not going to work as we require the sentences to make perfect sense.
