Google Map

I need to get a simple Google Map integration done. Look at this ([login to view URL]). I need a map like that which would pull address and categories from the database. All I would need is a map with 2 address in 2 different categories and when I click the icon on the map, it will show the address in the box. Put thank you when you big so that I know you have read this. NOTE: THIS IS NOT A HUGE PROJECT. I JUST WANTED A DEMO TO KNOW THAT YOU CAN DO GOOGLE MAPS. WHOMEVER IS CHOSEN FOR THIS PROJECT WILL BE BUILDING A BIGGER MAP WITH A BIGGER DATABASE.
