Couple of thoughts from my experience....
We use latest cutting edge
SEO techniques (approved by search engines).
Rarely is any "cutting edge" technique "approved by search engines."
I have ranked sites using straight, basic, old school SEO, and I've ranked sites using black hat stuff that will get them banned if they're caught (though I fully disclosed that to the site owner and let them make the decision).
We hire the best talent in this industry. With 250 Search Marketing experts, we have one of the largest Search Marketing team in the world.
They have 250 top experts but can't hire 1 decent copywriter? Not trying to be mean, but a lot of the copy on this site looks like it was written in India.
Under "Manual Link Requests to Related Sites" they state that they will create a reciprocal links page on your site with 450 related sites listed, and request links from them.
That is the LAST thing you want to do. Stuff like that gets sites penalized or banned altogether.
Also, most of the stuff done on that $1,500 package can be done within 5-10 hours. (Aside from the spam/link farming bit)
I notice that they skip some key things like article submission and press releases, because that would require actual work, creativity and learning about your niche. 
This is a ripoff and a half.

Google isn't as dumb as you think.
