Looking for Bilingual German/English Writer for Learning German Books (Long-term contract)

Hello! We are looking a new writer as we are expanding our language education books to the German Language. Therefore, we are looking for someone fully bilingual in both German and English and fully aware of grammar, word structure, word tenses, and so on. Big bonus if you've been working as a German teacher for non-native speakers. It's important to know that these books won't teach German in a normal textbook style. Instead, our books expect the reader to already have some basic knowledge of the language and instead tries to learn them German through stories and conversational stories. So this job requires some creative writing too as you will make up stories in German for the readers. The stories should also be written in English so it's important that you are 100% fluent in both languages so it looks good, correct and professional in both languages. We are looking for someone to work Long-term with and there will be many opportunities down the line as our German book brand is growing. You will be giving very clear instructions on the books and the size of each project ranges from 30-45k words. Every book should be written ideally within 4 weeks from starting date. We are paying $17 per 1000 words for this project and depending on quality and service we can increase this for projects after. Don't apply for this job unless you've done the Upwork grammar tests for both German and English and please give us a sample of both English and German jobs you've done, ideally, the same text. Please start your application with the word "rainbow" so I know you've read the full description of this job. Regards,
