Desktop application based on Google Maps- reposted

Project reposted, since I had to change some of the requirements. All freelancers interested are invited to bid again. Programming language C#. The application needed should be desktop based and use Google API to calculate routes with multiple stops. We could have addresses, cities or zip codes for input. The information needed is: -total distance of the trip -directions - distance traveled in every state of US for the certain trip ( the application will be used for trips in USA only and I won't actually travel so no offers with GPS solution) Other very important requirement is displaying Google maps in the application with the option to zoom in and out and adjust the trip by moving the way points. The same way you can do that in the webpage if you want to change the route. After we have the desired route chosen the application should deliver the information above. We get the total distance and directions first , than the traveled distance in every US state. How this will be done? Since google doesn't provide the intersection points of routes with state lines, I have that in SQL database. Every entry has coordinates( latitude/longitude), name of route(s), name of state line. From the direction response we will know the name of the route when state line is crossed, so we can find the point in the database. This information will serve as destination. The app will run another trip and get the total distance in the first state. After that this point will become start location in finding the distance in the next state. And so on for every state until reaching the final destination. Happy bidding !
