Sci-Fi Book Cover Artist Wanted, Multiple Covers Per Month (Show Me Your Work)

I publish sci-fi books and I need a cover artist for ongoing work. If the style is right, this is multiple covers per month, every month, long term.

I am looking for one specific art style. I have attached four covers as examples. This is exactly the look I want: clean, bold, high contrast, with every element clearly separated from the others, bright saturated color, and a strong subject that reads even at small thumbnail size. Please study them before replying.

Important: do not tell me how good you are. Show me. I will only consider you if you attach examples of your own past work that already match this style. Links or images, real covers or personal pieces, it does not matter, but I need to see proof that you can produce this look. Replies without examples will be ignored.

If your samples fit, we move fast and I will keep you busy.
