Why hire SEO companies who fail to bring their own site to the Top 10 for Google Search Engine Placement? Google's Top 10 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 10 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 10 is close to zero.
