Email Database / Directory

I posted this project before but the winner disappeared - that is why it is re-posted. I want to make a data base so that people can find people by email that they have lost touch with. People will make an account and put their details in i.e. First Name, Middle Name, Last Name, Country of Birth, Towns they have lived in, schools and colleges that they have been to, places that they have worked etc. Then if I search the data base for John Doe Born in New York or Worked At IBM, then all John Does that match those criteria will be displayed - but it will only show the information that I put in about John Doe, not information that is in his account that I did not know. This is to help stop identity theft. Then if I think I have found the John Doe that I want to contact - I will hit a CONTACT button and my details will be sent to John Doe saying that this person would like to contact you, - would you like to send him your email address YES - No. John Doe can then eiher contact me, as my email will have been sent to him, or he can say YES and his email address will be sent to me or he can say NO. We will obviously need a web page that explains how it all works. The data base and automation to make it work. I have written a lot but it is not a complicated project. Please bid and put anyother thoughts that you have in PMB.
