2-day teacher for summer camp students from China (8/4-8/5 on campus)

I am looking for 2 teachers (native English speaker) for a group of middle school students from China during the weekend of 8/4-8/5. There will be about 20 students from the summer camp, and each teacher will take care half of them during the class. The teaching topic can be American culture, US middle school life, introduction of US college, preparation and application process for US college, and so on. You are welcome to propose your own topic, and the idea is to communicate with the students in English and also help them learn some interesting and useful content.
The class will be 2 days (8/4 and 8/5), 3 hours in the morning and 3 hours in the afternoon for each day. The pay is $25/hour in cash. The class will be on campus (indoor and outdoor).
If you are interested, please contact me at wujunbo@gmail.com. Thanks.
