I am early in the process of making a radical invention of equipment for moving earth. At the moment I am having trouble estimating the cost of moving one ton of earth one kilometer in a setting where thousands of tons are moved. Getting the earth into the truck does not need to be included as it would be the same with or without my invention. Rough estimates without any references are alright as I have no idea on how to go about estimating this.
If you, instead of explaining me how I could estimate this, could tell me where I could obtain the real numbers, I would be delighted. I have tried asking companies, but they want all the details before they can make any rough indication of the price, and I do not want to deceive them to think that I would really buy the service from them.
