Pitch book for a mining project

I'm looking to create a comprehensive pitch book for a mining project. My goal is to use the pitch book to secure funding from investors and other stakeholders. I don't have a specific format in mind, so I need guidance on how best to structure the pitch book - most of the content has been written. I'm expecting the document to be 10-15 pages in length. This project will require a highly experienced freelancer in creating pitch books and securing investor funding. An informative, well-structured, visually engaging and compelling pitch book is necessary to draw in interested investors and stakeholders.
