I'm developing an ecommerce site to sell digital content in greater china and will use mPay ( http://www.mpay.com.hk ) as the payment gateway. As you can see in the attached file, interacting with their gateway is pretty straightforward.

I could spend the time learning how to hook this up to ubercart but I'd rather leave it to the mavens in this forum.

If you are interested please contact me and give me a rough idea of how much this would cost.
