mashup to my site

Install a map to a fresh drupal site. The map is to function as a directory for North America helping visitors find services in an area. The map will have hundreds of points on a view depending on the zoom. The entire database will have more than 500,000 locations when fully developed. I have a custom js from another webmaster. The script will need a little tweaking for my site but the bulk of the js is done. Google maps provides a format for an XML file with markers, so you will have to create one in using a php file, and then use the GDownloadUrl function to parse it out. [You can enter HTML in the box above][1] ## Deliverables The js is from [login to view URL] It is fast and should suit my purposes with a bit of tweaking. The major difference will be that there will be upto 1000 locations in a city not only 25. I have tried gmaps module and found it to be far too slow for my purposes. The majority of the data will be imported from excel, so this will be a consideration in the development of the site. If you are a js expert with knowledge of drupal I look forward to reviewing your experience and bid. See the attachement for specific details.
