Master's Student Research - Finding Foreign Interviewees Working in Korea

Hi, as you could guess in the title of the post, I am Korean but someone who is finding interviewees for the research about what does Korea society or law that makes foreigners’ life difficult. However finding a platform or just finding a person who is willing to do this is very, very, very hard. Even we send out gift cards and interviews fees. Is there any place that I could get help with this matter?
