Application with custom routes using Google Maps Api

I need someone expert in Google Maps Api to finish an unfinished project. The aplication shows groups, filtered by user, of custom routes defined by website's owner and Point of Interest in a google map. Aditionally the user is able to add his own route to the map and print it. Points of interests are png, stored on the website, shown on the map. Each route and point of interest on the map has a text description on html that has to be shown on a tooltip. Also routes are drawn in different color depending on the filtering and other criteria. Map zoom is set depending in the routes and points of interest that are shown on the map. The utility has two parts: - Frontend. Currently not worling properly - Route filtering utility - Map with more filters. - Map printing utility - PHP Filter utility - Backend. (Working properly) - Route adition - Route modification - Route deletion - Point of interest adition - Point of interest deletion - Point of interest modification I need someone who can get the job done. All the server side programming is ready and developed in LAMP. The provider has to be able to finish the client side and be able to make modification on the php code if needed. He'll have to check that frontend and backend are properly working. Client side programming has to be IE7,8, FF3 and Safari compatible. The sooner it gets finished the better... as always :-) If you are interested bid and I'll send link to current version. Mariano
