To answer your question: There are lots of tools that can automate this, but that's a good way to get your new site sandboxed. Don't mess with these unless you really know what you're doing.
If this site is a long-term investment for you, then you need to get your blog up and running. It will take a while to see results, but this is generally the core link-building engine of any organization. Establish a budget and get good writers. The links will [slowly] come.
Some of the more innocuous link-building methods that you can actively pursue are social media (pinterest & squidoo especially), newsworthy press-releases, social bookmarking, niche blog commenting, niche & high PR directories (both free & paid), and guest blogging / article directories. However, most of these things are dependent on content. The more content that you have (and the better that it is), the easier it becomes to build links.
Creating special offers can also work out well if you can get on various "employee discount" pages from reputable sites. If you have a brick-and-mortar business, local citations will also help to get you going.
I hope this helps.
