Add Google Maps API to my website

I need google maps embedded into my website ( [login to view URL] ) Specifically for the property details page. Google Maps will automatically map out exact location for each property a user might view. I am not well versed enough with implementing Google Maps api to take on this project myself (do not want to break anything). I know it is a rather quick job for someone well versed (Approx. 1 hour job) I am hoping to have this done ASAP. Thank you Note: View Gif attached to see approx layout I would like to see when installed. Current Prop. details page does not have map.
