Creating a Store Locator with PHP, MySQL & Google Maps

I need to create a store locator for my online store. I would like you to use google maps API and have the ability to add and remove stores by street address. I am not looking for a plug-in but stand alone coding to pull from a database. I will need the coding to be able to pull the LAT and LNG, and not have to provide it. I would also like to use custom flags for the locations & not the generic ones provided. [login to view URL] Tasks: 1.) Creating the Table 2.) Populating the Table - The table attach does not have LAT & LNG associated with the location. These will need to be populated from The Google Geocoding API [login to view URL] and hard coded when it comes time to add new locations 3.) Finding Locations with MySQL 4.) Outputting XML with PHP 5.) Creating the Map 6.) User Location Milestones: 1.) 25% of payment released when database is verified 2.) 50% of payment released when first draft of UI is published to test site - Requirements -- Add and remove locations using backend UI -- Adding locations does not require LAT & LNG -- Search produces accurate location of stores -- Users location works for search parameters 3.) 25% of payment released when final version of store locator is published to site
