Partitioning Job - Bulwer, KZN, 4001

I am moving to a new flat with one bedroom, im staying with my son. I need to partition a lounge to make a space for my son bedroom. I just need one wall that will close a small space to allow a small bedroom for my son. If I estimate, I am going to need five meter wall and a door space. I would like to know how much it will cost me.
