Despite many variables, I believe a general synopsis should be plausible from just a few details... A well dressed, somewhat well spoken sales man knocks on doors offering a pre thanksgiving "prep" promotion for house cleaning. He has a great attitude. The neighborhood isn't familiar with his company. The company is brand new. He works his way through upper-middle class neighborhoods without any references. People tend to find his demeanor as trustworthy and professional. He has a flyer that is clean and informative. The flyer offers a 25% discount. The rate is not mentioned in the flyer. The rate offered before the 25% discount is $30/hour for one time cleanup, and is reduced according to contract terms. He covers 500 houses, and speaks with 80 householders over the course of 5 days.
Alternative: Same flyer, sent to 5,000 homes via mail. All business would be taken by inbound phone calls, which the same sales man would use a script to set an appointment.
