Illustrator/InDesign Document Styling Updates

I am looking for a competent artworker who can adapt 230 A4 pages, split across multiple files into a new brand style.

We have a suit of technical datasheets that have been set in a particular style. This client has rebranded and therefore these documents need adjusting to fit with the new brand identity. A template exists that can be followed, editable Illustrator artwork and InDesign files will be supplied.

We will require the updated files supplied back as both editable documents in their original file format and as PDFs suitable for upload to a website.

There are 5 multi-page InDesign files, the rest are single or multi-page Illustrator files and they use a range of languages - mostly English and German, plus a handful in French and Dutch. Competency in the languages themselves is not required, but the ability to ensure the correct characters and accents are maintained is crucial.

Each document will require a reference number adding and specific filename format.

We have a hard deadline of end of April to finish this.
