We can execute this project on Agile methodology because sharing upfront estimate for such requirement will be technically not feasible. First we can do simple demo to get data for each platform and once that is done then after we can discuss app flow and plan ahead. Please let me know once you are online so we can discuss in detail and move ahead.
