Looking for headhunters

I have a recruitment agency specialized in language jobs. Currently i am looking for freelance headhunters in Germany who can help us with finding German speaking candidates who want to work abroad. At the moment we have clients in Czech Republic, Portugal, Greece and Poland. The job positions are mostly in customer service and accounting field. To find the right candidates you can post advertisements on job websites and use social media. For each hired candidate we pay a fixed commission and the amount is based on the country where the candidate is hired.
