Google Maps Based (for messaging) plugin

Hello.

Anyone knows about a plugin (if not, a way to solve this) that could have a functionality like this:

1. Messaging with google maps
2. The user must select at least two points in map (pickup and delivery location) but if needed more delivery points (ie. pickup location: my house, but need to go to market, then to the mall, then to garden etc .. and finally to my uncle’s house to finalize the service)
3. the price of the service is calculated according to distance.
4. the user can select a date to make the “reservation” of the service.

This may be a very specific functionality, i have been searching without success and i am new in WordPress and don’t want to start coding without being sure that there’s not an alternative to make this easier.

Thank you all.
