Customize a Google or Mapquest map for a Leisure website

This project is for a local Leisure and Activities booking website. It's based off a shopping cart software running on PHP, and MySQL + Few Ajax features What I would like to do is this: - whatever product show in a page (wether it's a search results, category page, etc…), these products will show dynamically in a mini-map depending on what filters the user changes. Once the user clicks on the mini map expand icon, a full screen map opens and the filters choice will be duplicated on the left side of the map. Basically what I'm looking to achieve you can see in those examples: - [login to view URL] - http://www.travelocity.com/experiencefinder/#subSection=Maps|section=Tools|destinationId=108 Please let me know your thoughts and I'll provide you with more details.
