Google themselves say to be wary of SEO companies that guarantee to get you to number one on Google:
Beware of SEOs that claim to guarantee rankings, allege a “special relationship” with Google, or advertise a “priority submit” to Google.
There is no priority submit for Google.
In fact, the only way to submit a site to Google directly is through our Add URL page or through the Google Sitemaps program, and you can do this yourself at no cost whatsoever.
