Hello
I can help you with your approach, I have access to a gigantic Arab political newspaper that attracts 250,000 unique visitors each day! the majority of traffic come from USA, Canada, Western Europe, Australia, New Zealand (high income countries), the other portion come from rich Middle Eastern Countries and the rest of the world, high percentage of those people are highly educated and speak English in addition to many foreign languages like French, Spanish, Italian, German, Greek and others, I don't guarantee hundreds of purchases but I can assure you thousands of visitors and tens of newsletter subscribers, this ad runs for 30 days.
The cost of the ad is high but trust me, it's well worth it! it will be in the news line in front of every visitor! so you'll get millions of impressions, I can also tailor an Article in Arabic to be published on that online magazine's server and explaining what your product is all about, this is a tested method that has proven higher conversion in the past.
Please contact me if interested.
