Find an experienced builder in Frankston South

I’ve installed posts in an embankment in my backyard for retaining walls. I can do the walls but need stairs made from bottom to top of the embankment. Stairs will be made of same timber sleepers as retaining wall. Posts are in already. See pics. I can help as a labourer for the job too. I will provide materials. Just need someone who knows how to do this to help me get it done. Hopefully just a days work. I’ll put up the rest of the walls. - Due date: Flexible
