Modify Wordpress theme

hi, on website [login to view URL] i need the modify: 1) enter geolocation for cities in search filters ( support indicate: Google Autocomplete : In this you don't need to add locations manually but to use the Google API service to load autocomplete locations from their API. That feature is built for SEARCHES but not for the user profiles. Once you will add locations from backend they will appear n drop down. You can use the Find on map field to use autocomplete feature from here : [login to view URL] and copy the same on above Address field. Hope this is clear to you. If you need to make the Country and City field Autocomplete than that can be possible via customization, let me know if you need to know the file for it.) 2) replace texts in Italian and make some changes as in the attached word file. 3) enter the key to update the theme automatically themeforest 4) under the personal card of the candidates as normal users, must appear the prewiew of the premium accounts as advertising, while in the personal profiles of the premium accounts will not appear advertising.
