What’s wrong with using academics or students?
Teaching a foreign language is a demanding activity that requires a special set of skills. However these are rarely the same as those needed to produce a smooth, stylish and appropriate translation. Professional translators are first and foremost writers, capable of producing texts that read well in the target language. If you would not consider using a student to write your original text, then don’t use a student to translate it, even though this may seem like an inexpensive option.
