Geodjango Google Maps query and reporting

A website where a user can create stackable queries on a number of datasets to display suburbs that match query criteria. Visual representation will be an Ajax-enabled webapp that utilises Google Maps API and Google Charts to display heatmap polygons, marker points, and line/bar/pie charts. The software will be developed on a standalone VMWare image running bitnami's GeoDjangoStack with Postgresql database. The developer is expected to have previous experience particularly in geodjango and Google Maps. Note: The app has been developed to an extent already within the VMWare with database schema established and Geodjango models for datasets created. A requirements document has been developed.
