Refer to the Scenario Below to Answer the Following Questions

Refer to the scenario below to answer the following questions. John Mayes opened Sparkle Janitorial in 1999. John began by acquiring two contracts for office cleaning services from two local manufacturing facilities. For two years, John and his wife, Barb, performed the cleaning services alone. After acquiring three additional cleaning contracts in 2001, John hired two employees.
"Up to that point, we had room to grow but we really had no advertising plan," John stated. "We were relying mostly on word-of-mouth."
By 2003, Barb hired another two full-time employees to begin Sparkle's new endeavor: carpet cleaning in homes and offices.
"Competition was getting tough for both of our services at that point," Barb added. "We ran a local radio spot three times each week. Then we had an advertiser print coupons on placemats. That gave us a little more exposure." John and Barb Mayes admit that they never realized the value of a sound promotional plan before now. "We wish we would have put together something catchy with a jingle way before now," they said.
