Do any of you have any tips on finding privates in South Korea for extra cash? I was thinking of getting an esl job at a public school which has reg hours everyday: usually 8-4. Then I'll get a part time job at a hagwan in the evening 6-9. How do you recommend i go about approaching a Korean hagwan director for this? In person? By email? Will he/she realize that it's "under the table" work I'm seeking without having to display a song and dance?
