Verification of French product translations with SEO adjustments

Good day, I will have the translations of product descriptions (average of 1 Word page, sometimes a little less, sometimes a little more) revised along with adjusting them in terms of SEO. The translations will be done by GPT chat, so they need proofreading before proceeding. It will also be necessary to define the right keywords for users who speak French but live in Switzerland, select those with the strongest potential and weave them into the content. Please quote me a rate per text, including proofreading and customization services, using the following text as an example. Of course, if other texts will be longer/shorter - together we will adjust the pricing accordingly.
