Contact Name & Email Collection From Niche Web Sites

I need to gather contact information from niche web sites so I can contact them about joining our affiliate marketing program. I need to do web searches for 300 keyword strings and collect the first 10-15 web sites along with the email and contact information. This data needs to be entered into excel. I will provide the layout. The reason I am doing this is so I can email the contact about joining our affiliate marketing campaign. Some keyword searches will result in the same listing of web sites. I need unique records. If you're interested please contact me with any questions.
