Because he is one of OIO affiliate..lulz. But honestly, OIOpublisher is a great program. If you want free then go for openX. There are also something similar to OIO but free. Unfortunately I forgot the name of that script.
We ( Ohana Media - Indian Ad Network ) are primarily looking for publishers with traffic from these following regions. India, Middle East and Soth East Asia. If you have considerable traffic from these regions and have some analytics data or demographics data, you can contact us.
Why don't you place few ads on different sites advertising you want to sell ad space. I just looked at bunch of ads and their sites and if they had advertising ad or tab on their site, it got my attention.

If you have one, PM me, willing to pay for an ad free offer not a paid one!
