If you're from an English speaking country, maybe a part time English teaching gig would work best for you. Pay should be about 30.000 KRW (34 AUD) per hour or at least that's what I've been offered by a hagwon owner (private school) for part time teaching when traveling to Japan to renew my tourist visa. FWIW I'm not from an English speaking country.
