eBook Formatting for KDP

I need two eBooks formatted for the KDP store. Currently, the formatting is off, and I need it adjusted to look great- they are in KDP but for some reason the formatting looks good, you need to add in contents page too.

Requirements:
- Correct text alignment, image placement, and margins/spacing
- Apply provided fonts and sizes

Ideal Skills and Experience:
- Proficient in Adobe Illustrator
- Experience with KDP formatting
