Can individuals without a BA teach English in South Korea?   If you are a South Korean citizen, you may go from school to school and offer your English teaching skills.  Obviously, as you don’t have a BA, schools will pay you less for teaching English.  You may, however, be able to find an English teaching assignment because you don’t need a work visa.   With excellent English skills and a four-week, on-site TEFL training with teaching practicum, doors to a TEFL teacher position may open for you over there.

     There is an on-line university out there designed to accommodate those who cannot afford to pay for higher education.  College professors of famous schools have come together to form the University of the People: http://www.uopeople.edu/.  Their goal is to enable access to good education for everyone.  This university is fully accredited in the United States, and the transfer credits are even accepted by such Ivy-League schools as Columbia University in New York City.  

     Study towards your BA almost free of charge and take an on-site TEFL program with teaching practicum.  While you are studying to complete  your degree on line, you may teach English in countries that accept English teachers without a college degree, based only on excellent English skills  and a high school diploma.  These countries include, but are not limited to, Cambodia, some South American countries, and countries on the African continent.   With some extra effort, you will be well on your way to a profitable English teaching job with a good salary/benefit package in a South Korean school, once you have completed your degree on line.
