I'm currently an international student at the University of South Australia, as well as a certified Neuro-Linguistic Programming coach & trainer.
Your job listing mentions a need for someone who can handle live phone calls. I am a local Vietanmese and I have been a fluent English speaker since young, with the band score of 7.5 in the IELTS test.
I have worked with many overseas agencies (Prudential Malaysia, Super Coach Incorporation Singapore). With the experience of working closely alongside international agencies, I'm extremely familiar to live translation, especially through online meetings. Furthermore, I have had extensive experience in making sales calls and customer service through my previous position at a language center.
For the above reasons, I believe I would be the ideal candidate for your project.
