copy and paste script

I need someone to build a script that will take information from a financial website (briefing.com. I will provide passowrd) and based on symbols and dates in Excel will copy and paste certain news articles into a word document. For instance, if the Excel spreadsheet says GSIC 2/7/2005, the script will have to find the news articles with the words GSIC on 2/7/2005, and paste it into a word document. It will also have to go and check news articles that have been written on GSIC for a few days prior to 2/7/2005, and paste those into the word document. Preferably the script/applet will run locally on my Windows box rather than being mounted at an ISP etc. Simple program.
