Book Cover Adjustment for BookVault

I am in the final stages of a Christian Book for teens and young adults that I am writing. I need an existing book jacket cover adjusted to fit BookVault parameters. The current cover is in PDF format from Ingram Spark, and designed with specific fonts and images that must be retained. I would prefer to work with someone who is a Christian who shares my values.

Adjustments required:
- Spine width
- Trim size
- Bleed areas

Ideal skills and experience:
- Proficiency in Adobe Acrobat or similar PDF editing tools
- Experience with book cover design and adjustments
- Attention to detail to ensure fonts and images remain intact
