Not trying to put a damper on your thoughts about starting an electrical construction type company in Saudi, but your chances will be slim to none!! You need ''contacts'' you need plenty, and i do mean plenty of cash too. The only work that needs full qualifications etc, will be on ''Prestige'' projects, and the chances of an unknown company getting those sorts of contracts will be Zero!!
The reason as stated why British and other Western electricians is cost!! You cannot compete with the third country nationals. Don't believe everything you here about these guy's, quite a few are very switched on guy's and would put a good many Domestic installers and even electricians from the UK to shame. Some are Engineers/Technicians working as electricians, because they can earn more in a week, than they can in a month in there own countries!! Every now and then there may be a contract for an electrical supervisor, who will be supervising these TCNs, but these day's they are very few and far between i'm afraid!!
Going back to your idea of starting a company in Saudi, ...you wouldn't believe the hoops you would need to go through, even just to get in to Saudi, let alone start a business. The Saudis love paperwork and official stamps, trouble is ....getting hold of them ...lol!!
Even the last time i was over there, any Western electrician's i came across were working on specialist systems that there company was installing, they were all on temporary entry/exist visa's not working visa's.
I can't see that Malcolm can tell you any different to be honest, the good old day's of working in Saudi is well and truly over!! They also haven't got the money that had in those day's either. Couple that, to the underlying countries infrastructure has all but been completed, and you can see, now a days, most projects in that part of the world is now Private projects, rather as than was in the past, Government projects!!
