Step-by-step "how to draw" lesson illustrations (layered) — ongoing work

'm building a drawing app and need progressive "how to draw" tutorial art — ongoing, potentially 20–50+ lessons over time. Per lesson: one subject (animals, anime, objects, etc.) built up in ~8–12 stages so a beginner can follow: 1. Construction guides (light-red oval + center cross / proportion lines) 2–5. Line-art stages (rough → clean outline) 2. Flat base colors 7–8. Shading & highlights Deliverables: a layered PSD (one layer/group per step) + one transparent PNG exported per step. Rights: Work-for-hire — full commercial copyright transfers to me on payment. Process: I'd like to start with 1 paid test lesson to lock the style/format, then commission in batches. I'll send reference images of the exact style I want. Please reply with: your portfolio, your price for the test lesson, and your per-lesson rate in bulk.
