Extension and interior design of 4000 sq ft house

I am looking for a professional freelancer to help me with the extension and interior design of my 4000 sq ft house. The areas I would like to focus on include the living room and kitchen, bedrooms and bathrooms, and outdoor spaces. The plan is to use mainly wood for the materials with a traditional design style. This project requires an experienced individual to utilize their skills in the areas of space layout and design, as well as the selection of appropriate materials. I am looking for someone who has an understanding for the beauty and functionality of good design, and can bring to life my vision for this home.
