Decking PUKEKOHE

We have just had a builder go off with Covid. We need four posts put in to put one ready made deck on, posts have been put in for another deck and just need the deck placed on it and the third deck which is 30 square metres needs posts put in and decked. It has already been levelled, some posts temp put in and holes dug. I would expect this would be two- three days work. and we are paying $50 per hour.
