Working visa for South Korea

I am a filipino and the philippine government through Philippine Overseas Employment Administration deploy workers in S.Korea. I am 42 years old, eager to work in Korea, but there is an age restriction there. Only 38 years old and below can work in S. Korea. How would I still work in Korea with the help of a Sponsor Employer? According to the government of Korea, a Filipino applicant worker must pass their Test on Korean Language Proficiency and wait for their advise for their employer. But, I have an employer already, but unable to take the Korean Test because of my age. How can I work in Korea without taking the said test and get employment/ working visa? i hope u could help me on this! Thank you very much.
