Threading is an ancient form of hair removal predominant in South Asia
and The Middle East. A special cotton thread from India is used to
remove the hair from its follicle.  I need to know where I can find
the labor pool for threading artists in Southern California.  At the
very least, please provide me with a list of indian periodicals with
current want ads for threading artists in Southern California. 
Generous tip will be provided if you can answer the  first part of the
question.  Thanks in advance.

Here are a couple of links with some resources for threading salons,
which provides resources globally, but you can choose to just view
California:
