Pixel-Art MMO Avatar Creation & Integration

I'm building an isometric social MMO (pixel-art style, Habbo-like) on Phaser 3 + Colyseus (TypeScript). I need an experienced 2D game artist + integrator to deliver a working player avatar.

Scope:

One base character (chibi proportions, I'll provide reference art) as an 8-directional sprite (S, SE, E, NE, N, NW, W, SW) — idle + walk cycle.
Pixel-art / clean 2D style that fits an isometric pixel world (2:1 tiles, ~26.57°).
Delivered as sprite sheets + JSON atlas, with a consistent foot anchor across all directions and frames (no bobbing/sliding when turning or walking).
Integration into my existing Phaser/Colyseus setup: the avatar must render by player facing (facing → direction sprite) and play idle/walk based on movement. I can give repo access or a clear spec.

Must-have experience:

Isometric games, 8-direction character sprites, sprite-sheet/atlas pipelines.
Phaser 3 (bonus: Colyseus).
Portfolio with directional animated characters (please link specific examples).

Nice to have (future phase, quote separately):

Modular/paper-doll layered clothing system (swappable hair/top/bottom/accessories registered across all directions).

Deliverables: source files (PSD/Aseprite), exported sprite sheets + JSON, and integration code or clear integration support.
Please quote: (a) base avatar 8-dir idle+walk, (b) integration, (c) optional modular system separately. Include timeline and 2-3 relevant portfolio links.
