Google Maps "Pinch to zoom" enabled on mobile devices

Hello, I am looking for a coder who can add the "pinch to zoom" function on google maps for my wordpress website. My website is already complete however I am in need of adding this feature since the theme author did not include this. My website: [login to view URL] The theme I'm using is: [login to view URL] The "pinch to zoom" feature needs to be added to the maps including the one on the main page. Here is the exact feature I want integrated: [login to view URL] Since the theme support doesn't offer assistance in telling me which file to edit and which lines to add or edit, I will need to find someone here. One coder also already told me which line to delete in my theme's files. After I deleted this line the pinch to zoom works but stops working once the screen overlay appears saying "use two fingers to swipe". Hence why I am in need of minor help once more. If all goes well, I also have one more small project that I don't mind outsourcing. Thank you.
