What kind of offer should I give to my old employer for some lawn accounts? He is getting out of lawn care completely, and focusing on home remodeling. I talked to him and he said he had at least 3 accounts he could give me maybe a few more. What kind of deal should we work out? Should I give him a one time fee or a percentage of the lawn? If it's a percentage, how long do we continue the deal? I'm not going to pay him forever.
