Warmest greetings!
This is Sukjoon Jun, a South Korean citizen who is a freelancer translator and assistant who has been very active in other freelancing platform, UPW0RK. (I can share my profile there if you'd like. I am getting getting started at Freelancer.com.)
I have been helping western clients to sort their issues with the Koreans or Korean companies for years. I think for your case, I could translate and send emails to cafe24's support. I also worked as a web designer years ago so I could perhaps better understand your issue better than others.
I hope to start working for you soon!
Best regards,
Jun
