Why hire SEO companies who fail to bring their own site to the Top 20 for Google Search Engine Placement? Google's Top 20 positions is where 95% of all business on Google and 60% of all the search engines is done.

Comparing search engine ranking by their prices is irrelevant. Perhaps more than 40 sites compete with you now for the Top 20 locations and they have search engine optimization similar to what you are being offered. Your chance of being # 41 is very high, and your chance to be one of the Top 20 is close to zero.
