I'm a small owner/ operator with 1-2 employees. I bid and do all the work. I see the trees, plan the work, then work the plan.
I figure my rigging points, order of execution of work, etc.
Different people will work different ways. Maybe some more pics and notes from the sales person to the foreman might help. The foreman would at least have a heads up going into it, for maximum efficiency.
I, personally, can't imagine only selling without occasional on-the-crew time to know their abilities/ productivity/ etc, or at least checking in on the crew at work, or knowing how many crew-hours went into each bid job, allowing some calibration for the estimator.
Sorta like always trying to accurately judge weight on crane picks without ever doing them, or more simply, accurately cutting 16" firewood rounds without ever checking against a true 16" measure.
In the end, unless its hitting their pocketbook, they are not going to change. I like the commission/ compensation based on the estimated crew hours matching the estimated hours. I figure that their should be a bonus for the crew as well when they beat the estimator's hours while still doing a quality job, with no call-backs.
