Build a Login/Registration Section for my website

Hi - I want a registration/login webpage for my website. I want this solution in ONE DAY .... THIS IS AN URGENT REQUEST When user registers the 1) data should be stored in my sql server DB (not my sql) 2) the user should get an email confirmation 3) Ability to change password, reset password 4) After successful registration and login the user should be able to edit user information (like user name, DOB, address, email and contact number) 5) Send unique Alphanumeric number for each registered user (this will be unique number for him along with email - I need both to be unique) 6) Ability to use reference while registration - if a new user is registering he should be able to see an optional field to enter reference number (alphanumeric created in step 5) or email 7) all the information should be stored in DB Login Section: 1) once logged they should be redirected to home page itself 2) but they should be able to see their name and log out on the top right corner - I mean before login they see login/Registration on home page top right corner but after login they see Username / Logout 3) When they click on username there should be a drop down menu showing two sections a) Profile - should be able to edit profile. b) My References - Shows list of people used his reference.
