Research on model maker wages

Hi,

I’m currently working on a research and feasibility of a project,
and need some info concerning wages and related taxes. Hope to
find help from Orchid:

What I need to know is as follow:

1- What is the average hourly rate for an experienced model
maker --working only with wax-- to produce a piece of jewelry
from a design?

2- What is the average hourly rate for an experienced model
maker --working only with metals-- to produce a piece of jewelry
from a design?

3- The above questions are for wages paid in the USA, Canada,
India, Singapore, Hong Kong and China.

4- What are the taxes directly associated to wages and how much
do they amount for? (i.e. for every $1 paid for wages, how much
is paid in taxes in the above-mentioned countries?)

Thank you all for the help.
