I am in sales and have a sales prospecting database in MS Excel that
contains approximately 500 company names. This will grow to 1000 names
eventually. I would like to subscribe to a news clipping service that
will track these 500 names. Yahoo and Google alerts provide
sufficiently good results. The problem is they have a web interface
that requires each of the 500 prospects to be entered individually.

Is there any service out there that will allow a bulk update (In some
delimited format) that can do this data entry for me? I'd even be
willing to pay up to $10-20/month. If there's not a service out there
that will do this, is there a "screen scraping" tool/technique (or
other technical method) to do this bulk update?
