construction estimate

As a business owner, I am looking for a professional freelancer to provide an accurate and detailed construction estimate for an industrial project that I have in mind. To ensure that my specific preferences are met, I would like the freelancer to take into account information such as specified materials and methods. The size or scope of the project I am looking to have estimated is of a small-scale, such as a room renovation. Ultimately, this estimate should offer me a clear understanding of what materials and processes are needed to complete the construction project and help me plan accordingly.
