Translation for Catalogue into German – native speakers only

We’re looking for someone who is native speaking German to translate our product catalogue into German.
The catalogue is 90 pages and has approximately, 4 products per page. So we are looking for translations for approximately 360 products. The text for translation will be provided in an excel spreadsheet and we will want the translated product name and translated body copy to be added into two separate columns on the sheet alongside the English version.
This MUST NOT be generated by automated translation software as the finished article must be grammatically correct in the translation. We will be checking if the copy is correct in other languages with native German speakers in the business.
Please provide a quote for this work.
