As you know it all depends on the layout of those acres, and the obstacles that come with it. Also you know your numbers and how much you need to make for your time spent on a property per man hour. I learned a long time ago that it doesn't matter how many yards you have if at the end of the day your not making any money. So don't sell yourself short just to get work if all its going to be is busy work. But I guess your looking for numbers for a price so someone else may chime in who might help you with that.
