Pergola and plinth required - Landscaping job in Norwich, Norfolk

Job description

Hi, I would like a pergola fitted on a raised plinth at the bottom of my garden, the ground is very uneven as I live on a hill, so it would have to levelled first, and access to the garden is through a single sized garage with steps, therefore it will be manual work as machinery will not fit through garage. Ideally the plinth I would like it edged with sleepers and then the top, bricked or slabbed. Please I would like some idea to the cost of this project. Thankyou
