Yes, 12K using a 120 ton crane.
I don't care if they laugh, cry, or have a heart attack, but if I get the job I they better pay. Local low bidding hack told them 6K, let him have it.
As far as hours on the job goes... I think that if I had a 4 man crew with all good guys on the ground I could have it brushed out in a day, and have the wood down in another day... but then you still have to get that big stuff out of there, and you can't go over the septic... and going through the woods repeatedly with heavy equipment would be tough.
