Cad drawings for pre engineered building

I am looking to hire a Freelancer to produce CAD drawings for a pre-engineered large building. The drawings are intended for construction purposes and I have specific requirements that need to be met. The scale of the building is large, such as an industrial warehouse or office building. The freelancer must be experienced in designing these types of structures, to ensure accuracy and quality in the drawings produced. The bid should include all relevant information related to the project, including estimated timeline for delivery and cost.
