Add Contact to Yahoo/Gmail/Hotmail

Hi, I was looking at a function to that does "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 this is somthing you can do. Serious Bidders only. ## Deliverables A simple web page with three icons. One each for yahoo/hotmail/gmail. When user clicks on an icon it will ask their login/password. After authentication it will redirect users where they can see two things. 1. A button "Add us to your address book". On clicking this button you need to add a new contact (e.g test <test@[login to view URL]>) in their address book. 2. A grid view that list all the contacts present in their address book.
