Multilingual Language Instruction

I am the owner of lingovato.com
A language service website
I need language teachers to explain educational videos for courses in these languages
Spanish
German
French
Italian
Chinese
The candidate must be an excellent English speaking because the language of instruction is English.
For example, I need a native German, speaking English to explain the videos of German course.
I have about 12 files in each language course, I offer 250 usd per language for all files.
