Excavating/digging work

Hello, Wondering if any construction digger is around who can help with digging the ground (highlighted space in below picture) for building retaining wall? Location - Porirua(weekend/weekdays any day would be ok) Things are costing very high from the builder who is building our house so want to look at other available options. For the depth level for digging, attached the second picture of retaining wall for idea. We may need some soil to be left at the back of the land to fill some lower level of ground. Looking for work done sooner then later. Happy to meet up at site if you want to look and quote.
