What are the best niches to target for a lead generation qualification nurturing offer in the Middle East, or should it be more general? Is that a good start?

I don't really think that whether you're doing it in the Middle East or somewhere else matters; it's more about human psychology. I understand there are slight cultural differences in how offers are received, but geography shouldn't slow you down—it's often just an excuse. People sometimes say, 'Everything works in your country but not in mine,' and assume you're American, but I'm English and work in the American market, which is a competitive advantage. However, you don't need to be American to make a lot of money; the same approaches that work in American markets work elsewhere because they rely on human beings and psychology, which are similar everywhere. I've already answered this question before, but hopefully that gives you some context.
