You ask a very good question and especially timely with another discussion going on right now. I can't help you with answers to your questions, but I do strongly urge you to get some help no matter what you have to do or pay so you do not become one of the people that comes back later with a story of how they were cheated.
That forester/mill company may just have a great deal for you and have the most honorable intentions, but you do need some professional help to advise you and get the best deal in your interest.
Ron Scott may just be the forester you need if he is available and close to you.
