You might be able to make very good money from the lumber, but it might not be worth anything since it's been on the ground 2 years.
I'd get somebody local who knows wood to take a look at it and give you an opinion. If the wood is still good then it needs to get up off the ground as soon as possible. You might put a request for help in at the forestry forum, it's a trust worthy group of people.
