Adding Contact to Gmail/Hotmail/Yahoo

Hi, I was looking at a function to do "Add us to your contacts" for gmail/yahoo/hotmail/msn. Basically I want our cutomers to come on our website and click on yahoo/gmail/hotmail/msn icon. when they click on icon we ask for their login/passwords. Once they give us these info we automatically add our contact details in their address book. Let me know if you can do that. Only serious bidders pls. No time wasters. ## Deliverables More Details are as under: Create one web page with three icons. One each for yahoo, gmail and hotmail. When user clicks on any of the icon, they will be prompted to enter their username and password ( two textboxes ). Once they will enter user name and password they will be authenticated and a new contact ( e.g 'Abc, XYZ' <abc@[login to view URL]> ) will be created in their address book. There will be a grid/listing on the page showing all their contacts in the address book.
