allso depends from that part of the world u want a person from.
Nothern europe : more expensive, but in many means , have better understanding of trends, computers, design ect
Southe Europe / usa : same as above but probably a bit cheaper
old est block : in many regards, good, but havent been on the internet wave as long as europe/usa, and can be a problem ( i know theres alot of very good webmasters from that area, i'm just saying if you pick out someone at random, theres a bigger chance of getting a noob than in other areas :D )
asia : cheaper - but their culture is very differend. Have done buissness with design and programming companies in India, Indonesia ect - and must say i will not do that again, unless i know from others, that we work in a good way.
My exp has shown that deadlines and feedback, isnt valued as high as in usa/europe
If I had to do a fulltime job, i wouldt ask something like 5500 $
But i allso have education is this field - have been a webmaster for 5 + years, do gfx and 3d
but i'm not looking for a job
do make that money in other ways with less working hours that 7-8 hours a day
