car wash preliminary design

I am looking for a professional to help with the preliminary design for a car wash. The project includes exterior washing only and is in bay car wash. The size of the car wash is medium (3 self-serve bays and 2 automatic bays). The budget for this project is flexible; I am open to proposals for any budget that meets my requirements. I will need someone to provide a comprehensive design that takes into account all relevant aspects of an in-bay car wash, including safety measures, maintenance, site-plans, operational costs, and consumer access. This design must be suitable for scale, growth, and a competitive market. It must pass planning and zoning approval. The location has been selected
