ENGLISH TEACHING JOB

I am a Quantity Surveyor and I have been teaching constrution students for four years.I aquired a chinese visa last year to teach in china but did not make the trip because the institute did not find a replcement.I have decided to do it this year.I dont have a teaching qualification but I have the experience and I am capable of teaching english at any secondary,elementary or any lower class because English is my first language.
