2D furniture layout, door size and location for the second floor

I am in need of a freelancer who can create a 2D furniture layout for my second floor space, which is approximately 300 sqm. I prefer a modern style for the furnishings, but I am open to any suggestions for the door size and location on the second floor. I am looking for someone with experience in creating functional and aesthetically pleasing furniture layouts, and who can provide creative solutions for optimizing the use of space. The ideal candidate should have a strong attention to detail and be able to work efficiently to produce a high-quality design within a reasonable timeframe.
