Upon receiving a request, the seller may submit a response to the request, as desired. Additionally, the invention provides a forum for the negotiation of any agreemments and the formation of contracts to provide the requested, or alternative goods/services (106). Further, the present invention provides a system and process for targeting marketing to online buyers based upon profiles established for the buyers, profiles for the sellers, and the current on-line activities of a buyer.
