Outside Storage

I have a quick project need. We are looking to build RV, trailer, auto and boat storage solution on our property. I am looking to have a more professional rendering completed of the entire space and some close up drawings of what the buildout looks like. What we have is a space that is 400 foot deep running South at the bottom to North at the top. The width is 335 feet from West to East. The height of the structure will be 15 foot, with support beams every 26 feet. I am looking to have a high level full layout top down view similar to the provided rough sketch. Also are some examples of what the structure will look like from the front and side. All distances on the documents are feet.
I am needing a quick turnaround so ask as many questions as needed and show any samples or concepts.
