The reviews on Google places are added from within Google, so this is not a function built into Vantage (I believe you actually have to log in with a Google account in order to add the review).
In the payment settings, you can charge for listings, as well as charge for featured ads, or for an ad to feature in the category. You can see the options for this in the
Vantage admin demo.
The other features you wish to add are not existing features of Vantage and would currently require some customization of the theme on your part. Our themes are not encrypted, so you are free to make changes of this nature if you wish, however we do recommend the use of a child theme which will prevent you losing these modifications when an upgrade is carried out. Thanks.
