I am an American with nearly ten years of experience in Korea. I am on an E2 visa. I can send you my resume and some recent photos.
I prefer elementary through middle school. I am available ASAP.
You might want to talk to a previous employer I have references.
If you have any questions feel free to message me.  I look forward to hearing from you soon.

should you really be posting photos of young students without the permission of their parents..?

Presumably he means photos of himself not his students.

Don't take a 2,1 million won job because you drive down the wages when you do that.  Ask for upper 2.0's at least, especially if you have 10 years experience.  Respect yourself.
