Do you have to mow it or are you just pushing it up? Don't sell yourself short if you have to haul material plus bring in machines or extra labor. That's not an acre but I'd price it a little higher so you feel better about spending more time if needed. Could get in there and find stumps or the cherry could be rotten and fall apart taking longer to clean up than if it was logs. No dump fees?
