What would be useful to know is how many lesson plans/week will you be required to prepare?
Big money, yes. Very busy, yes.
Compare working in Shanxi, public sector through agent - I got 5000 a month in the boondocks for 16 classes, most 45 minutes, but some just 40 minutes/week teaching at an average senior high, grade 2, with a Chinese t/a present. One lesson plan/week, regurgitate it up to 16 times, classes over 3 days, Monday- Wednesday. No make-up classes! When students had exams, I was on 8/week or 6/week. Full pay, very easy job, bags of free time, so low salary, but still more than twice what my Chinese colleagues were on! Cost of living, 1500/month, supporting Chinese wife there with me, drinking beer, 5 big bottles/day and smoking! Cost of living in rural place very cheap, and, last but not least, virtually no chance of being fired!
However, as you like! I just posted this so you can get an idea of teaching in the public sector.
