Ebook cover and editable file

Hi, I am looking to have an ebook cover designed that I can change the title and background colour of, when I promote something new, keeping consistency.

Please see attached examples. I will need the editable in something like photoshop or illustrator.

I like the design of the attached examples, where there is some framing around the number, a clear title, credibility with a 5 star review etc which I would like to mirror in our own style.

The design must be super professional like the examples.

If you feel you are a good fit, please reach out. I will want to be able to change the background colours from orange, to green, to pink etc, also invert where necessary when on a dark background.

Please provide examples of your ebook cover work.

Thanks
Steve
