I came across this site while researching more info on business development.
Goliath Business Knowledge on Demand (
http://goliath.ecnext.com/sales-leads/) is a service where you can search for business leads by location, demographics and industry. The charge per lead is $0.20 which isn't too bad and there is a $10.00 minimum charge. For those of you who like developing business by direct mail, this may be a very good resource for you.
