You claim that you're looking for someone who's experienced in a field that isn't even within the grasp of most Saudis in terms qualifications.
I don't really understand the meaning of posting such job listings in a forum that's obviously geared towards a sub-population that isn't trully qualified for the position you're offering. Are you ridiculing the desperate people who are so eager to sustain themselves like me?

I am 100% certain that you'll never hire someone who's Saudi no matter how highly qualified he is. You're just posting this job out of ridicule.

Assuming that you're the hiring person behind the ad and not just someone delegating it.

Terrible times we live in these days.
