AJAX Google Driving Directions

Hi, I'm looking for an AJAX coder to right a script that will allow my directory users to dynamically add waypoints from zip code search results to generate driving directions. The business directory script called phpmydirectory which has a zip db included. Additionally, I have google map libraries puchased from code322 that have prebuilt modules for generating driving directions from waypoints however no ajax components included to save this results in a session. This project will add google maps with waypoints/directions to the existing phpmydirectory script. A user will access this new functionality within the phpmydirectory business script two ways; within a listing detail page to find nearby listings, and as a geo search that a user could filter by radius. When the user clicks on the marker I would like them to see the underlying listing info in one tab and listing description in a second tab. One additional customization is that I would like the user to have the ability to save the waypoints/directions to their preferences. The customization I would need from you is a simple save or bookmark feature with update to a user preferences table that I would provide. Also, I would handle the output of the save waypoints/directions within the existing user profile/admin module. Here is a sample of google search results clipping with save to server.
