About a year ago, I learned about something that's available for FREE (got your attention, right?) at the local library. It's a database of businesses in the US & Canada called ReferenceUSA. It's possible that your library already subscribes to this database (mine does). With my free library card, I can access this database (from my laptop at home, no less) and generate lists of potential clients. It's amazing and pretty easy to use. You can sort that huge list of businesses by annual revenue, metro area, # of employees, SIC code (a 6-digit code that classifies various types of bussinesses), etc. etc.
Here's an example: I've used this database to generate a list of ad agencies, located in Seattle, with between 5 & 20 employees, and revenues of between $5M & $20M. The database then spits out TONS of info like company name, contact name, address, phone #, website, credit rating, .... more info than you'll ever use. Isn't that GREAT??!
Call your library and check it out.
And let me know if it works for you.
