Take down 2 walls of my house in Noordhoek Cape Town

Hi, we are looking for someone who can take down two walls in our house. One external wall (not a supporting wall it's just a random wall the juts out), and one internal wall (not sure if it's a supporting wall). We also need the person to build a pillar in place of one of the walls to match another pillar in the house - hope that makes sense. Thank you. Nicci
