We have a super pair of blokes who will spend all day reducing/removing trees to our specification, for a flat rate of £350 per day. They swing around up there like Tarzan. They'll even cut some of the wood small enough for firewood if they have time. They'll either leave or take away stuff for free, whatever we decide, and they chip all the tops. We've had to have them two or three times over the last few years as we've lost some big trees to Dutch Elm disease. They deeply understand trees are are full of good advice.
