Hey Matthew,
As Keri mentioned below, we have no affiliation or special arrangement with Moz, the logo was intended to reference our post on YouMoz. This has now been rectified, sorry about any confusion caused there! 
In regards to whether our services will be good for your site, we assume you are talking about our flagship service, Blogger Outreach.
Put simply, we outreach to genuine websites and make content placements, relevant to your target website. We wrote a post explaining some of the ways you can go about blogger outreach, some of which we use ourselves:
http://fatjoe.co/blogger-outreach-hacks/ - This should give you a good insight on how to find opportunities
Putting the link building moral debate aside, how effective/safe these links are will depend on your overall strategy. This may be something an SEO agency or consultancy can help you with.
Hope this helps.
