But do bear in mind the hourly rates for some of the language schools here - you get paid when you are teaching. Pre class prep and post class tidying up come out of your time. And you may find you are teaching in 3 different centres in HK over the course of a day - travel time comes out of your time too. And if you teach a class from 9 - 10, and then 10:30-11:30, you will only get paid for 2 hours whereas in reality you may have arrived to set up around 8:45, had 30 minutes between the lessons and then finished getting rid of the kids, tidying up etc by 11:45, in fact 3 hours of work.
So you might be commuting or working for 9 hours in a day, but only pick up those rates for 4 or so hours of that time.
Of course there are permanent English teaching roles here for people with little or no English teaching experience, but expect around 1000 pounds a month upwards.
This is only feedback from friends of mine I have in HK that teach english, not my first hand experience. But the point they have made to me is that a rate of, say HK$250 an hour, does not translate into $10,000 a week (ie 40 hours x $250). $5-6k a week would be closer to the mark so probably better to budget on that as the real rate might be nearer to around half the quoted rate for the time you put in.
This may seem obvious to some but I come from an IT background where hourly rate tended to translate into 40 paid hours a week.
Of course there will be others on here with more experience than I have but I thought I would share this with you as it may help your budgeting. If any of you contract teachers out there know of better rates, or schools that do pay high rates for 8 hour days please let me know and I can forward it on to some of my chums.
