Minimalist Luxury townhouse Interior Design

I have a multi unit development. I require interior design done to 1 unit. This needs to include kitchen, bathroom, living area, powder room, master bedroom only. The design needs to be minimalist, all neutral colours, natural stone, linear mosaic tiles etc... (Budget: $250 - $750 AUD, Jobs: 3D Modelling, 3D Rendering, 3D Visualization, AutoCAD, Home Design, Interior Design, Lighting Design, Print Design, Revit, SketchUp)
