Verification of Italian product translations with SEO customization

Good morning, I would like to commission the verification of product description translations (on average 1 Word page, sometimes a bit less, sometimes a bit more) along with their optimization in terms of SEO. The translations will be done by Chat GPT, so they require corrections before starting work. It will also be necessary to define the appropriate keywords for users who speak German but live in Switzerland, choose those with the strongest potential, and incorporate them into the content. Please provide a rate for one text, including the verification and optimization service, using the example of the text below. Of course, if other texts are longer/shorter - we will adjust the pricing accordingly together.
