I enjoy small projects (I consider this to fit), and I am interested in learning as well (as a topic), so I would love to work on this project for you.
I usually work monochrome, so tones are my focus, but I really like this idea you have, and I can definitely find ways to add color to make certain limited aspects "pop." In my opinion, the specific colors matter much less if you know how to apply tones (which is my focus).
I have a vision for this of how you want it to look (hopefully it's the same) of a cross-section cloud-campus and each section would have more detail up-close.
Assuming each "task" is one image, I would say $65 each, and of course you would see everything at the sketch stage, so I could move forward after you approve it. From your request, I could easily make 7+ images, but I only see for sure you requested 1-2 (one for home page and perhaps one for the student page). I have only set my bid for completing 1 image.
I look forward to this, and please contact me so we can get started. Thank you for posting.
