Hi Ya,
Not too sure on this one but it may be worth having a look at the following link:
http://www.tunisia.com/Tunisia/Busin...iness-projects
Kris has given lots of good info and links to other sites that may help.
I cant remember right now the other website that has more information I will try to find it, but also have a look in google search - I live in Megrine and its one of the largest industrial areas, if you type Megrine into google it will give you lots of company info and contacts for steel, IT etc, my brother-in-law starts a job in December at an Oil rig so Ill try to find out from him too.
Anyway sorry if this is not much help!
