Given the fact that the URL you provided feels a bit like a squeeze page (highly focused sales landing page), I would be careful.
I've been working with organic SEO for over a decade and I put my days of linking building well behind me. I did this a few years ago and I'm very happy I did.
Instead of searching for link building opportunities, focus more on producing high quality content and growing your presence on social media. Make sure you share content across various social media channels including LinkedIn, Twitter, and Google+ for B2B and Facebook, Twitter, Pinterest and Instagram for B2C. If you do not have any strong images, then skip Pinterest and Instagram.
If you write educational content that is geared towards your target market and their needs, the links will come naturally.
This is a safe way of building links and one which will survive the test of time and future Google algorithm changes.
