Ebook cover

I am writing a 30,000 word non fiction book about gut health. After looking at most of the book covers that are on page one Amazon under gut health, I realized that I need something different as most designs are similar and not to my liking. I would like a catchy cover with vibrant colour that catches the eye. I have a vision of an image of a gut in the centre of the cover with my main title inside it. I thought about having 6 outer circles with text inside relating what causes gut problems but have been told that the text would be unreadable once Amazon makes a thumbnail of your cover. If there is anyone out there that could do such a cover for me, I would love to hear from you. I have uploaded a sample of what I think I want obviously not the same colours.
