Create a Mobile TRANSPORTATION Website/App

Please do not submit inquiries to me without speaking about details in this project specifically. This is real simple. I help people discover the life of using a bicycle as their PRIMARY commuting vehicle. I say "primary" because they will also use public transportation (bus, rail). The problem is, all transportation websites and apps (like google maps) only show directions on how to walk to the nearest bus stop. Yes, they show a bicycle route as an option, but they don't show a combination of biking to the buses. Go to [login to view URL] and plug in any address and get directions to another address, then you'll see it gives the options to either Drive, Walk, Bike, or Bus. When you select the option to use a Bus, it only gives you results and time for what it takes to walk to the bus stop, and walk off the bus to your final destination. My users will be biking to the bus stop and then biking again once exiting the bus. I need to provide a solution that will show people directions assuming they are going to bike instead of walk. Please talk to me about how you will create this app or mobile website, and costs.
