Spine 4.2 Character Animation (4 PSD Characters)

I have 4 PSD character files that need to be prepared and animated in Spine 4.2.
Requirements:
Front-facing 2D skeletal animation (no 360°/turntable).
Create:
1 subtle Idle Loop (breathing, mist drift, secondary motion)
1 Win Loop (1–1.5s seamless loop with eye flare, mist surge, slight cape/coat movement)
Layer characters puppet-style with separate parts: eyes, eye glow, head, hair, collar, coat/cape, jewelry, and mist.
Deliver Spine 4.2 source files and animation exports.
Please share relevant Spine animation examples and your estimated completion time.
