BIG bits of oak tree trunk (London Rd, HW HP11)

Hi there,
I need a very large piece of oak.
It would have to be at least 2.5m (8’6”) long and 650mm (26”) thick.
I don’t have a means to lift it so would need to be able to chop it up with a chainsaw (into long slabs) wherever it currently lies.
Much thanks,
Nick
