Google API Routing

Hi, we have a project that we'd like you to work on. 2 or more locations put onto a map- it then calculates the halfway point or center based off the time it takes to get there with traffic, etc. i would like the form to have that fancy automatic google address checker and that's about it. the default is 2 address fields, then a little + button to add more locations- well responsive for all devices as well. It will return back a list of all the POI's in that area There needs to be 3 buttons with 3 different calculations- 1. quickest- quickest meetup 2. equal time- everyone travels the same amount of time 3. equal distance- everyone travels the same distance
