Build a beta version of a "carbon footprint" application

The application we would like to develop aims to make people aware of their carbon footprint when they travel, commute, etc. It aims to raise awareness about the environment and what they can contribute. It would be a simple interface, with one major functionality. As a user, you would have to enter your departure and arrival addresses. The algorithm/server then proposes the different means of locomotion and what they consume in carbon. The different options are: public transport, car, bicycle, and walking distance. The application also proposes the travel time according to the chosen means of transportation in order to stay in the spectrum of efficiency.

With the budget we have been given, this application will be a working prototype since we understand that the server requires more funds to run it consistently.

We are therefore looking for a simple and functional beta version of this idea. Please accept the offer or propose a new one.
