German and Dutch Content Improvement and Proofreading

We are looking for German and Dutch native speakers to do thorough proofreading of two websites and improve on how the content reads and also insert keywords that will be provided. The content was written by non-natives in the form of a translation of the English website and hence may not read well for Germans and Dutch.

The sites are as follows:
- https://storm-protector.de/
- https://www.storm-protector.nl/

The project encompasses two products: shelters and replacement covers. Each of these categories has three products, but those are just size variations - the text is the same, so we only need two product pages to be improved. We also need the text on the category page and the about us pages improved. The total amount of text on these pages is 1705 words.
I can supply you with a list of keywords and the end goal is to make the text read well and have some of these keywords in it. You will have the liberty to change the text if it is easier than trying to make the current translation work.
The budget is per website and I am looking for two people - one for German and one for Dutch.
