As everyone else in this forum has said, you know, getting a Google+ listing is key to developing your local business. But in addition to your Google places listing, make sure you add up to 10 images, you add videos. Make sure your description in Google places really makes sense and really describes your business well. And the other thing you're going to need for Google+ is citations, so citations is really a listing in a local directories. And what it has to do, you have to have the exact name, address and phone number that's in your Google+ listing, in all these different citation sites or these local directories.
That will go a long way in helping you to increase your presence on local listings.
