Keep an eye on Inquisix
Here's an interesting new product, just into beta: Inquisix. This is a service for sales people who need a more effective alternative to cold calling to generate leads.

I've looked at the product (even though I am not a 'prospect' myself) and it makes a lot of sense. You may want to check it out - they are taking beta applications.
