Develop a routing application for physically challenged persons to travel in IIT Bombay campus and reach various places such as academic areas, hostels, etc.. You can also propose new paths, roads and other required facilities

I am looking for a developer to create a routing application specifically designed for physically challenged persons to travel in IIT Bombay campus and reach various places such as academic areas, hostels, etc. My preferred mode of transportation for people that are physically challenged is wheelchair and I require the application to have real-time navigation. Unfortunately, I do not have access to detailed maps and plans of the IIT Bombay campus. This application should include new paths, roads, and other relevant facilities required to make travelling easier and more accessible.
