Limestone Retaining Walls Perth

Located in Perth and 1.8meters high, all the ideas on the figure Ball Park?

You do not know if it is a help, but I live in Montreal and my concrete block retaining wall which is nearly 6 feet tall and 50 feet wide and cost me $ 7000 Canadian. I got a discount because of the same company has done all my landscaping, but you are looking for a price much doubt.

You can see an example of some of my wall here ....
