Assist me with Bulk Marketing

I have a spreadsheet with about 8,500 rows of visitor data to our website. Most of the entries have the hostname and/or organization name of the visitor as well as pages visited and other info. For this list, I would like you to remove all of rows that only show the visitor's telecom/ISP name (and not their company name). Then, for the remaining rows that do show a legitimate company name, I would like you to locate contact information (title, direct-dial phone number, email, etc.) for several contacts at that company (using the company website, [login to view URL], linkedin or other sources). I will provide a "key" indicating what kind of contacts we would prefer based on the pages visited (for example, if the page visited was "[login to view URL]" we might want technical contacts, but if it was "[login to view URL]" we might want marketing contacts).
