"Locate Me" function with Google Maps API & Ajax

We are looking for an experienced indiviudal that can develop a single functionality for our local search platform. Within the attached page, we would like our user to be able to set their current location. Therefore we provide a text input field where one can enter a his current location (e.g. "oak road new york"). If the google maps api returns a single result, this should be used for submission via the form. If the google maps api returns more results (see the "did you mean:" results when searching for "oak road new york" ) we would like to display the "did you mean" options within the div class="didYouMean" so that the user can make his choice and the result is used for submission via the form. Since this functionality is on a page with several forms, we do not want the page to reload. Therefore the functionality should be implemented as AJAX. I am sure someone has already invented such a functionality so it should be easy to apply it to our needs. Deliverables are: - documented solution within our provided LocateMe page - HTML & JS We are looking forward to your quotes!
