Realistic Animal Kingdom Colouring Series

I’m putting together an eight-book colouring series for children aged 6-8 that moves through different animal “kingdoms.” Book 1 will feature dinosaurs, followed by bears, tigers, lions, and four more groups we’ll define together. What I need from you: • 30–35 interior pages per book, each page built around a detailed yet age-appropriate realistic illustration ready for KDP trim size 8.5" × 11". • A balanced mix in every book: straight colouring spreads, dot-to-dot scenes that resolve into the main illustration, and a few simple word-search or matching-style puzzles that tie back to the featured animals. • A cohesive, eye-catching front cover for each volume that makes it obvious these belong to one series (consistent typography, badge, and footer), while still giving every animal group its own look. • Print-ready PDF interiors plus layered source files (PSD or AI) and high-resolution PNGs, and back-cover text; supply artwork, layout, and puzzle logic. All files must meet KDP bleed, margin, and color specs and pass their pre-press checker. Please outline your workflow, the software you’ll use, and roughly how long you’ll need per book so we can set milestones for draft sketches, final line art, and finished layouts. If you have previous KDP examples in a realistic style, feel free to link them.
