Integrated destination sales system with ASP-hosted member interface

An integrated computerized sales system for destination events includes a member user interface (MUI) hosted by an application service provider (ASP) and accessible to a plurality of independent service providers that are members of a convention visitor bureau (CVB) organization. Members periodically log into the MUI to review information on a request for proposal (RFP) from a potential destination event organizer. The MUI includes a tentative response booking agreement (TRBA) electronic form to be completed by a member for any services responsive to the RFP that the member is willing to make available. A projected service availability database automatically incorporates information from the TRBA and is accessible only by the CVB. The projected service availability database is reviewed by the CVB in order to prepare a response to the RFP that includes information about services from members of the CVB that is then communicated to the potential destination event organizer.
