I agree with Moviefrontier. There is no way for you to find out if the SEO service company that you hire will do the SEO work manually or automatically.
A simple link building is definitely good for your site, but one way link building would make no significant difference in the long term. We must try every possible means to obtain relevant quality links as possible if you want to get the best possible result at the end.
