Illusrator For a Sci Fi Book

My book happens in an apocalyptic word. I need someone who can create a cover for the front and back page. In the front there will be a technological city from some other species on Earth before us. And in the back page there will be an apocalyptic city. The city is covered by white glowing plants and ivies and it is about 40 years after the global destruction. There will be also a kind of flying space ship and some other flying islands in the air. The cities in the front page are very advanced and covered by transparent shields. The back page is a destroyed city covered by plants. The old plants are dead and the new life forms are white and glowing. People need masks to live in that environment. If you believe you can do that can you please let me know? I have a few more books and I will need more of your work if we make a good deal. I will also put your name in my book as the illustrator. My advanced cities are covered by shields or domes. They are transparent. There are many cities like that and they are more likely glowing with a blue light from inside. It can look like an alien world. But it is on Earth. It was one million years ago. The apocalyptic cities are in this world. I have uploaded an image to picture the advanced one. You can also find the apocalyptic ones. The illustration must be realistic as much as it can be. I do not want some cartoon drawing. I will check your work and decide on this. If you can make a good work I will give you my other works as well. I have ten other books. Those pictures are samples. So you can see what kind of work I need.
