Edit German Translations for Tour company

We are a walking tour company in Ireland. We have 43 self-guided walking tours - see list here: https://walkinghikingireland.com/self-guided-walking-tours/ Each tour has introductory text at the top of the page below the image gallery - the amount differs per tour. The site has WPML installed and all tours have been translated into five languages using Google Translate. We would like a quotation to edit the German translations (introductory text only) for all self-guided walking tours - not all in one go but over a period of time to spread out the cost - depending on the cost per tour. Please provide a cost to edit one tour initially. Thank you.
