Knowing what you want from the worker is key, a sales rep is a company representative, liasing between the clients and the company, a salesman is there to get orders, two different roles often confused by an employer.
Since the OP's focus was money making, I assume you mean a salesman. What would I expect? Results, how they get them is not so important as long as nothing illegal etc takes place.
Lost count how many times I secured large orders in the evening or on a golf course in the daytime, or saved accounts by helping a client with cash flow problems. End of the day depending on your product or service, you will either want someone building relationships that last, or order chasers.
You might think a rep calling hundreds of clients a week is good from your perspective, but a single good call can make more money than hundreds of useless ones. How do you measure your current people?
