I believe 10% is a multi industry standard... So if the company grosses, with 1 crew, between 2k-3k/day=10-15k/week, the salesman makes between 50-75K/year... That sounds fair to me... Maybe more if he sets up and impliments a sucessful marketting program... based on increased profits.. I haven't met anyone that really knows marketting and really knows trees though...
I've often thought there must be guys out there that are great salesmen... I knew this one guy that sold deep root fertilization and root crown excavation and swing installation on a huge percentage of his jobs... He hated takedowns and tried to save almost every tree... I could recognize his work as soon as I stepped on a property...
I guess I'd have to really believe in something in order to sell it well... I'd like to sell organinc fertilization, soil remineralization/balancing etc... And though I believe in its benefits intellectually I haven't actually seen the results or read the convincing science... Same with radial trenching and lightening protection...
