English to Korean to English

Hello, I’m looking for a translator to work with me between my company and filmmakers in South Korea (potentially one in North Korea later, not sure how different the dialects may be, if at all – but we can focus on SK for now). Let me know if you are interested, I have 2 now and there will be more later.  

Btw, you would translate emails I want to send to them, which I will then send, then translate their replies (which I would copy and paste to you). Will take several email exchanges most times, though some may just say no on the first email and then we are done with that contact. But again, there are many contacts so this would be ongoing.
