Hi there,
The site looks new? How long has this been live? I've tried finding data, but, couldn't really find anything.
If the site is new and recently indexed, your on-page grade may reflect an A which is great news, however, you will have to go through the indexing process before entering in at all.
Secondly, you really need to also think about your off-page efforts. Remember, you will need quality inbound links from third party sites to drive link equity which is a huge factor in the ranking algorithm.
Work on producing exceptional content and post them up on your blog and share them on social networks. If you haven't set up Facebook/Twitter/Google+ it's high time you did, these can be great for building brand reputation, sharing your blog content with the end result of attracting quality links if your content is good enough.
Be patient with indexation, you will not fall to the first page overnight. Spend your time structuring the site correctly and then work on the off-site efforts by producing AWESOME content and sharing it with others - if the content hits the spot, the links will follow.
In the meantime to get the link equity ball rolling, maybe look at some niche blogs with good traffic and see if you can write for them some real good value-added content for their blog with a link back to you.
Good luck!
