You can hire employees long-term for a very low price in the Shenzhen-area
I know typical wages/salaries for local Shenzhen-area workers really well. I also know the salaries for different positions/jobs; I have lots of friends and read "Help Wanted" posters regularly every time I walk along the street. If you hire me I'll gladly share this information with you while you're here.
