PM Sender Project "FULL DETAIL THROUGH PM"

Hello Programmers around Gaf I need a tool programmed that would send Private Messages to the users of a website. I cannot disclose much in details. But once you have bidded. I will guide you and let you know what I exactly need and how we will go about it. Basically I want a PM sender that can send PM to members to sites where members can send and receive private messages from each other.
