The buying criteria inputs can specify an advertiser request to buy advertising placements on at least two remotely located media outlets. The method can associate an identifier to the quote, transmit the quote, store the identifier and the quote in an enterprise database, determine at least one quote acceptance constraint based on predetermined criteria, receive an acceptance communication in response to the quote, approve the acceptance communication based on the at least one quote acceptance constraint, and transmit instructions of advertising placements to the associated at least one remotely located media outlet. The approval can be associated with at least one remotely located media outlet.
