This will be an interesting project provided we have the correct flow.
We have to start the ppt by talking about the existing scenario of this location/vicinity(population, transport, climate etc.). Answering the question WHERE.
Then opportunity at hand which will include reasons for establishing this smart city, target audience, ROI. Answering WHY.
Finally a small customer research if possible with the targeted people who are wiling to relocate here for job opportunities and housing facilities. Answering WHO.
Let me know if this flow works.
