MBA and other admissions counseling work

Hi, I am considering moving to Korea and I would like to get work doing MBA counseling to help clients get into schools like Harvard and Stanford.  I am a graduate of Yale and Stanford and I have about five years experience getting Japanese clients into top ten US schools. I am great at getting flawed applicants into top schools.  I got a women into Stanford who only had a 580 gmat.   How would you recommend I get access to top clients in Korea?  In Japan, it worked entirely by word of mouth.
