Gardening

I need help with digging a small 50 cm trench to install a root barrier to stop bamboo in my garden from spreading. I have a petrol hand held digger to help with the work. Secondly I need help to dig away the lawn and the topsoil layer ( very small lawn) and then install limestone of 75mm and builder's sand for 30 mm in order to prepare the ground for laying artificial grass. The job will include the rolling of the limestone and sand as well as a requirement that the person has the skill to install the artificial grass. All tools and equipment will be supplied.
