I hope i am in the correct section.

I am a beginner in web development and trying to build a more complex site that i would like to add seating reservation. i wanted to use a 3rd party, however the problem is that none of them support South African Rand due to PayPal not supporting it. So i do have a payment processing company in my country that can do the payment processing but i still need to do my own seat reservations.

Where do i start to do this?
