ESL teacher. how to get a work Z visa legally?

Jess, if you want to be an ESL teacher in China, you should have a Bachelor's Degree as well as two years of working experience. If you don't have it, it may be hard to get the Foreigner Employment Permit and the Z type. Some agencies may have a way to get around this, but I am not sure whether the process is legal. You can contact it and see more details. Be careful and make a resonable judgement by yourself.
