Lottie Character Animation

Lottie Character Animation — Children's App Owl Character
I have an approved cartoon owl character (image attached). I need this converted into a set of Lottie JSON animation files for a Flutter mobile app.
Technical specs:

Canvas: 512×512px
Frame rate: 30fps
Transparent background
Optimised for Flutter lottie 2.x package
All easing: ease-in-out, no linear keyframes

I need 7 animation states:

Idle — seamless loop: gentle breathing (100%→103% scale), blink every 4 seconds, ear tufts sway gently
Speaking — beak opens and closes rhythmically while audio plays, seamless loop
Celebrating — wings raise, body hops, eyes become happy crescents, plays once then returns to idle
Thinking — character tilts 12° to one side, holds, returns, gentle loop
Worried — slow calm transition, eyes slightly larger and more attentive, gentle forward lean. Must feel warm and safe — NOT alarmed
Waving — one wing raises and waves twice, plays once then returns to idle
Entrance — character fades and scales in on app open, leads into idle

Deliverables:

Layered SVG of the character
7 individual Lottie JSON files (one per state)
1 combined JSON with all states as named markers for Flutter
Preview GIF showing all states

Please include Lottie portfolio links with your proposal.
