Abstract: A distributed computer network includes an item provider computer system maintaining at least one campaign in a database. The at least one campaign identifies a list of prospects operating businesses in a common industry that are within a specified geographical area. The item provider computer system runs a marketing and sales application that allows an item provider to electronically appoint a telemarketer for the at least one campaign and an agent for the at least one campaign. At least one telemarketer client computer system communicates with the item provider computer system over a secure Internet connection to enable the telemarketer to interact with the marketing and sales application. The telemarketer is provided with on-line access to the list of prospects in the database when the telemarketer is electronically appointed.
