Promotion of the group in Vkontakte

Good afternoon, I need to add a photographer to the VC. The group should be promoted within a small city and among a certain audience, i.e., the group should be promoted. To raise it to the top will not be very difficult, promoted groups of competitors not so much.
It's important! So that the promotion was safe for the group, so that it was not banned for spam, etc.
