tweak for Google maps page

Canadian firm seeks a vendor with sound expertise working with the Google maps api. We have already done 99% of the work: - a full screen map (a key component) - map markers added to highlight key cities - a floating <div> with logo and brief description We are looking for someone to add mouse-overs and on-click controls for these elements. Specifically: - when the city is moused over a popup dialogue appears, presenting a brief blurb as well as links to different, third-party websites - each city's popup will contain unique content - we would also like to be able to mark three key regions on the map with a translucent circle Our final deployment will be in a php environment. Experience working on similar projects in the past will get the job, as well as a quick turnaround. We will supply all of our code (a simple one-page php file), an experienced Google web developer will have no trouble with this project. Thanks, and happy bidding.
