Change book's layout/dimension from current to another

Job ID: 39763954

Budget: $10 – $30 USD

My book was already set for publishing - layout, design, illustrations added etc all done ✅️

Current Book size: 5.5" by 8.5"

But
A self publishing house I want to use accepts only standard A5 format dimensions in mm 145*205.

So I need to modify the layout according to those dimensions.

I need a professional that can change the size of my book without disturbing the style and content.

Current Full Book Spec:

➡️ Size: A5 ( 5.5" by 8.5" inches or
23.5 x 16 cm)
➡️ Volume approx 170/180 pp.
➡️ Black and white, 50 black and white illustrations, 80-weight paper
