If it's not as easy as just Googling some companies, and current data providers won't do it, then perhaps the best way to get 'real' data is a local phone book and a telemarketer calling businesses to gather information.

It's also a good time for the telemarketer to upsell the business from their 'free listing' to an enhanced listing.
