Hey Jacob sorry for the late reply as I'm in Florida. I second what Andrew said. 1 week still seems ambitious for 25 or so acres. I know it can sometimes be exciting and overwhelming to price these types of jobs but don't cut or sell your self short. Also I wouldn't recomend using your truck and trailer hauling debris all over the property. It is a quick way to beat the truck up. All in all it sounds like a great job and that you have a solid plan in place , just don't under estimate the time it will take. I would go for 2 weeks to be safe ( ie weather, break downs etc)
