Write down formal report about "keyword research".

I have to write down formal report. The organization I am consulting for is Arrow Exterminators (http://www.arrowexterminators.com/). My part is “Keyword Research”. You are to identify 20 targeted keywords/keyword phrases for the organization (aligned with your audience personas), provide justification for these words/phrases (i.e. why you have chosen them and not others), and present data regarding the volume of searches and any relevant trend data. You should use tools like

· Google Trends: http://www.google.com/trends/
