Lead generation website

I am looking for lead generation website through which firms can get leads on matching information basis.. i.e firms wiill sing up on website by filling relevant information and have a profile >> there will be user interface form where users will fill up a form with drop down menu details and the information that matches the FIRMS details will be emailed as a lead to the [login to view URL] lead will be stored in a report which website admin can later compile to see how many leads each form got which can be emailed to the firm. script will be in php + my sql and something like [login to view URL] Only final fixed bids will be accepted.
