Interior contractor boq

I'm looking to hire a professional and experienced interior contractor to provide a detailed bill of quantity (boq) for a commercial interior project. I have a clear vision of the design but need help putting it into action. The project covers 1-5 rooms/areas that require new furniture, decor, paint and more. The contractor must be able to accurately and precisely list all materials, labor, and transportation costs per room/area to provide the best estimates for the project. The bill of quantity should include any and all costs necessary to complete the project. It's important to me that the contractor have in-depth knowledge, expertise, and experience in commercial interior design/renovation projects.
