Geolocation wp plugin

I need a wp plugin? that will allow the administrator to input a list of addresses (up to 5) in the backend? and then... when the visitor comes to the page it will integrate with Google maps API to show them the nearest location TO THEM as well as map/directions from where they are now (current geolocation) to the NEAREST address (input in the backend by the admin) The admin should be able to create a input the map using a short code (i.e. [localmap]) OR create it's own url to be linked to from a custom menu ...IF this is the case, the plugin MUST state the url for the admin to link to from with in the plugin's admin page. The map should be formatted to fit in 326px wide space (to fit on mobile phones) Here are some references: [login to view URL] [login to view URL] [login to view URL] I already have a working (non wordpress plugin - just html version of this script [login to view URL] [login to view URL] ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
