Google maps for Drupal website

Add three types of Google maps to a travel website in development using Drupal 6. (1) Maps showing route from place A to place B with waypoints, like on [login to view URL] (2) Maps showing cluster of node locations, like on [login to view URL] (3) Ability to add a custom Google map to any node, with no popup balloon and zoom set appropriate to context (e.g. some maps will show a city on a country map, some will show a street in a city map, some may show a route within a city. All maps must be views or panels so they can be scaled and shown in a themable block and tailored for good presentation. Bidders must include examples of where they have produced similar functionality on other websites, or your bid will not be considered.
