Google Custom Search
First of all, the 100 free searches and $5.00 per 1000 queries you mentioned are for Custom Search API,
. 101 queries won't be charged for $5.00, instead, 101*0.005 = 50 cents.
The business group introduced in that blog post is for Google Site Search,
, where you sign up 1-year contract and pay up-front the estimated queries, starting from $100 for 20,000 searches.
