How are you guys charging for fert/insect/weed apps? Do you charge a per thousand rate or an hourly rate? Also, do you charge a flat rate or do you charge a rate + materials. We only have one guy in town right now, and he is charging a flat rate/1000 (materials are included in his rate). Also, if you are tank mixing fert, insecticide, and herbicide, are you chargin for 3 apps or one?
