Script to use DeepL API

We have a subscription for the DeepL API translation service. I am looking for a developer who can create a simple script to use their document translation feature for TXT files.

The documentation is described here:
https://www.deepl.com/docs-api/translating-documents/uploading/

So we only need the uploading / downloading feature for TXT files

Some example code's are described in this blog:
https://thenewstack.io/getting-started-with-the-deepl-language-translation-api-in-python/
Maybe others are available on the internet

Idea:
We upload files to directory on our server ("/to-be-translated")
Script picks up any files on the directory
Script deletes the files on the directory
Script downloads ready files to other folder (/transated")
