Google Maps Visitor IP Mapping on Wordpress Site

Hi - I'd like the ability to do the following on my landing page: 1) Have google maps automatically map the user's location and display it 2) Insert an overlay to display a 5 mile radius around the user's ip address 3) have a popup with some custom text and html inside 4) allow user to map update area, as needed This will be embedded on a wordpress page so it will need to be compatible. SAMPLE design attached. Please include examples of your work that relates to this project.
