Proofreading a website in German [native speakers only]

[IMPORTANT : We are looking for a German translator, not someone to grow our marketplace or do some coding, ONLY PROOFREADING]

We are a marketplace based in France and we are trying to expand to the German market !
You actually don't need to speak french for the job.

We are willing to have our German food packaging site proofread. It's already been translated by Deepl Pro, so the idea would be to check the translation and make it truly "native" if it sounds weird.

According to my calculations, you will have to proofread around 40,000 words.
I don't know exactly how many words need to be proofread, as there's a lot of repetition in the product descriptions in particular. The URL of the site is [covrpack.de]([URL visible pour les membres Pro]). Not everything need to be proofread, it is essentially the categories of the website, the overall user experience and product data sheets (around 140, with a lot of similar products with the exact same description).
Would it be possible for you to give me a quote by taking a quick look at the site to assess the price?
It would be easier if you already master the Shopify tool (the Langshop plug-in) so that you can translate directly on the site.

Have a nice day!
