Design a keyword program

I am looking for someone to create a very basic script that will pull information from the internet. I need it to be defined and specific to the U.S. for now. The search perameters will be based on key words only. I could be more specific with theses but would like some information regarding the issues that may come up. I would like to enter key words in the program and pull information like business name, address, website and such. I'm not sure about formating the output, but I would like to be able to extract the information into a usable spreadsheet or load it into a database.
