Google Maps Mash-up

I am looking for a Google Maps Mash-Up. The site uses php/mysql. First the script must check with google and makes sure the address is valid. If the address is valid, it will display a map. If 2 address are present the script will need to make sure that both addresses are valid, and display only the valid ones. If there are 2 valid addresses, both addresses need to be displayed with a sidebar with links. ## Deliverables As little javascript as possible should be used. The map should be containted within a div that can be modified later for styling. The width and the height of the sidebar should be very easy to change. Please message me with any questions you may have. Thanks!
