Need a a script and a database module that will allow a user to select a state on the United States map. The map will only add a marker where there is a current promotion.
We have a website that has fundraising promotions for several different organizations in the US. We want the visitors to be able to select a fundraiser by state and then the cities that are currently having promotions would appear and then they would be able to select the city to see the organizations holding fundraisers.
The backend should have an admin login where we can add new fundraising events and the map on the site would reflect those updates. I would like a php/asp solution. Does not have to be done from scratch, could be a commercial product or something that was created for others. Need to have an inexpensive solution asap.
