I need ebook cover designer

I'm looking for someone to create a children's book cover for my series. I want someone who would be in charge of the creativity and the design of the cover to make sure all the elements go together well. If you can mimic the exact art style, that would be great. If not, my team can the illustrations as long as you create a great cover design and layout. Please include the word Duper Supers on your proposal and send at least 2-3 samples of the book covers you have created in the past.

The price is $20 if you can mimic the characters. It will be $10 if my team has to do the main illustration.

We do need the cover in 3 different formats:
-Ebook Cover
-Print Cover
-3D Cover for advertisement
