I would start here in Linked in:

Also do some research.

I don't have a direct connection to someone hiring now but I will let you know if I do. Also feel free to ask any question.
There are also plenty of head hunters:

This is also a facebook page for factory jobs in South Korea
Thank you so much for the information (sorry for replying late. Been spending the weekend with my girlfriend). I will go throw them. If I do have questions hope you don't mind me reaching out?
I also took this weekend off to rest. Feel free to ask about language and or double check a company for history... Some are worse than others.
