I will tell you how to get more. Quit using an attorney to negotiate for you. Negotiate yourself and in person. Gather a copy of the legal agreement and make adjustments as you are necessary. It's far less intimidating than you think. Don't allow the company to tell you what the going rate is, talk to your neighbors. Figure out what they are getting paid, trust me pay will change from landowner to landowner depending on those that negotiate on their own or use an attorney to negotiate.
