Hiring a salesperson is the most painful hire in any business. Six months of salary before they produce. They leave after a year, often for a competitor.
The Sales Guy does the whole job. He hunts the right prospects. He runs the conversations. He handles the back and forth, the questions, the objections, the proposals.
He does not need motivation on a Monday. He does not lose interest after the third no. He works the pipeline every day, on every account that matters.
