What's the best way to sell information products in Nigeria? I'm talking about automated sales (digital downloads); what kind of payment platform, payment gateway, and Web interface would be best for this?

One is doing good with this for international sales, as it is quite easy to do that with the numerous USD payment processors/gateways as long as you have a PayPal account. But for information products targeted at the Nigerian market, I'm at a loss.

Anyone here has any experience with this?
