One of the local guys does this. He has an arrangement with the Lawn Dr. guy. All I know is the lawn service gets a small kickback as a referral fee I guess. What's the proper way to set up this arrangement and who makes what money? Is there a normal referral fee? I think the fert guy gives the lawn guy a discount (that's where the fee comes from) and the lawn guy charges the customer the normal amount...I think. Again, what's the best and fair way to make a business arrangement with an applicator?
