Hi there!
I am quite comfortable with scraping data from websites and would love to help you out with this.
Basically what I will do, is develop a program, either in Ruby or Perl, that will take as input your CSV file, search the term on Amazon, and produce another list with those terms with over 100 results.
I am available to start this project right now! I expect to be able to get you something by late tonight, or tomorrow.
I hope to be able to help you out with this!
