I have a problem essentially my current method of harvesting information related to prospective company contact information within my given marketing profile is extremely time consuming.
Does anyone have any experience or any recommendations for creating a streamline cost effective method of harvesting company contact information?
I use custom build datamining tool. It does search for potential companies in city, guesses their potential profile and produces offer. It pre-selects targets based on defined rule set. For example, companies using specific software solutions.
You can hire developer to do something to automate your current work.
DUNS number is the US, EU govs and many companies world wide do that.

Certificate of Good Standing is another good way to verify company.
