Interior Design Assistance for Small Flat

I’m looking for an interior designer to help me optimize my small flat, specifically the main living space (a 20-square-meter living room with an open kitchen). The kitchen layout is fixed, but I’d love to create a functional and stylish design that incorporates:

- A dedicated workspace (ideally one that can be hidden when not in use)
- A dining area
- No need for a TV space
- Recycling as much of my current furniture as possible, as finding a sofa that fits through the entry door is a challenge

Would this be something you could assist with? If so, could you provide an idea of your pricing?

Looking forward to your thoughts.
