Here are my thoughts, based on something I have heard here and there during BAC 2011.
If you are hunting for “whales” the countries Qatar & UAE are where you want to hunt. If you get a sheikh of some sort to register and play, you are pretty much set for life. Now these are just stories I’ve been told, do not know how much truth there’s is in them, but it sounds logical.
How you can specifically target that area I am not exactly sure, but even if someone knew I doubt they will share their strategy. Your bets bet will bet to pick a sport and start previewing local teams in Qatar and UAE, national teams as well.
Once these people are at your site, you can always try to convert them around other gambling markets, hence casino/bingo etc.
This is the only way I can think of.
