Ppt on construction process from site marking to complete constructed building

I am looking for a freelancer to create a formal and professional PowerPoint presentation regarding the construction process, from site marking to complete constructed building. The presentation should cover detailed steps of this process for the benefit of potential clients or customers. No content or images are available, so I need help with the creation of the content and images for the presentation accordingly. For the style, I prefer something formal and professional that will communicate the key points effectively.
