Ok !
if you want a list of companies , you can find on yellow.mu , or mtinfopages.com , mauritiusbusinessguide.com , ile-maurice.com directory.
another interesting place is the mcci.org i believe or a search on google stating mauritius chamber of commerce.
or the government portal www.gov.mu , searching for ministry of employment.
you may get a list also on ncb.intnet.mu !
GOod luck!
