A few problems here!
Looks very close to those trees. How close and how high are they?
It looks like it will also need a long strop (100 ft?). Also, if it's embedded in the mud, who is going to burrow under it to rig the load?
Not many civvy helicopters are capable of doing this job for you; not many even have underslung load hook equipment. Your best bet is to ask the RAF at Odiham if they can do it as a training exercise.
But I reckon it is best left there as an artificial reef...
Some time since I landed on the back lawn there at Hammerwood!
