How to find detailed contact information of prospective clients

[vitali]

Hi all!
We are working on a new online project and we need
specific information for its direct marketing.
Does anybody know yellowpages or business directories,
which provides full information about american
businesses - fields: name of contact person, phone
number and website URL and description are essential.
These business must have previous experience with
online marketing (pay money for traffic).
Or suggest, please, a way, the similar information can
be found in the Internet.

Thanks for all answers.

I use a company called:
Decide with Confidence
www.dnb.com

DNB provides what you are looking for and then some.

They provide a great number of tools. They even show what a company made in dollars in the past 1 - 2 years. Need a credit report on a company you want to do business with. They provide that also.
You can buy mailing lists such as physical mailing lists, and even target down which companies you need contacts from.

It has been a huge part of my businesses success. Great tool, and hope it fits what you are looking for.
