Active job

Small backyard excavation job

I need a trench dug that is approximately 6m long x 50cm wide x 50cm deep. I have done part of the job but hit old tree roots (the trees are long gone). I reckon I need someone with a really small excavator or some other serious tools. It's a tight spot and if a small excavator is used it would need to be capable of getting on to a deck that is only 40cm above ground (i.e. rubber runners & maybe ramps or couple of planks). See pics.
