Well, not being a coder/developer (are they the same thing?) i'm not excatly sure. Many years ago, self taught, i created an order processing system using Lotus Approach for my then business, but that's the extent of my knowledge.
i think a DApp built on Hive might be the best way to go.
To get some understanding of what would be needed, i guess you would need to read some of the posts about Matrix-8, then come back to me or @matrix-8 with questions.
I see the Matrix-8 Master Platform (which will be owned by no-one) ultimately being used by virtually the whole population of the planet (or at least those who have access to a smartphone or computer). Before that however some smaller organisations would choose to adopt a subway Matrix-8 platform for their own governance. I am trying to get Hive, Ecoin (over 1.5 million users - target 1 billion by the end of this year), and Initiative Q (well over 5 million users) plus others interested at the moment.
I think these three posts would be the best starting points:

I hope you will invest the time to begin to understand the huge potential of Matrix-8, and help us to get some idea of time and cost involved to create such a system.
Namaste
