You can find and purchase a country postal code database and send it to us so we can import to the product (because you've purchased a support). The database may be in sql, csv or xml format, must contain zip code, latitude and longitude.

Regarding the search field modification I guess you will find useful the following guide which is located at: http://www.iautosoftware.com/demo/doc/UserManual/html_listing_search_form_modificati.htm
