2d plans for a house of 90 m2

I am looking for a professional freelancer to help me with a 2D /3D plan for a granny flat of 90 m2 for an interior design project. I have a general idea of what I would like but I am looking to improve my rough design done on Roomsketcher and get some professional ideas. so I am looking to hire someone to create a plan that meets my vision. This project is estimated to be completed within a month's time. I need someone who has the experience, creativity, and attention to detail to make this project a success.
