share to social network

I need an existing website rebuilt. Social network advertisement set up: 1) after an action is completed by a member, the window will pop up to ask the member to share his status to his own social networks from a Merchant. 2) the status to be shared are preset pictures and preset slogan, or pictures taken by the members. 3) one member only can share one vip advertisement, the rest of the share will be ordinary post. 4) one member can share for same merchant only one a week.
