Project expectation: Swiggy,zomato. ( We expect the quality of the app to be at this level with ability to scale into large volume.)
Simple If you can deliver this then there is nothing to discuss. Concept and Prototype evaluation. Scaling Future expansion and UI element discussion and the project completion should be in 2 Months. Sorry No Delay 2 Months Only. I Need estimates, How you are planning to do. Language. And database expansion.
