Hi there
Here are some great articles to check out:

SEO Company Checklist: How to Hire the Right Vendor (Inc)
The Recommended List (Moz)
One thing I will say out of the gate - any company that says "first page of Google", ignore them. Any company that has strategies solely based on link building, ignore them. If something sounds TOO good to be true, it is. You'll get gut feelings talk to SEO companies - you can tell when someone has your best interest at heart and asks the right questions.
I would recommend as well that you take a look at the Learn section of Moz to educate yourself a bit as well. This way, you can hear red flags on basics and understand fundamentals in the industry.
Based on a very, very quick skim of the attached document, I would be questioning the Custom Backlink section. Here's a great article from Forbes on what not to do from a link building perspective. Also, Webmaster Tools shouldn't be "optional" - it's a must. Here's how to set those up from Google and Bing.
Hope this all helps a bit - good luck!
