location website

Hello the idea behind this project is that anyone can log into a website where they will be presented with a single page that shows a map of their current location. The user can then search for a specific address, or touch the screen to indicate their address Once their location is selected, they select an option from a required drop down menu, enter some optional details and then submit - this is not an app, simply a website. There is no logins / usernames etc ... the user simply opens the website, finds location and, selects an option and clicks submit that data is then sent to the appropriate client. So geofencing is required to ensure that notifications made in a specific area go to the right client of mine. i have set up a google account with the places and mapsjavascript api .. but will add / delete these as you direct me to I have mockups of the UI i want available on request
