Realistic 3D Dragon Animations

Hello,
I am developing a Dragon Casual Sim game in Unity. Since the game is entirely centered around dragons, I will need a large number of dragon animations.

I already have a ready-made dragon/Wyvern 3D model that I purchased from the Unity Asset Store. It already has:
A complete skeleton/rig
A Unity Avatar
An Animator Controller
Several ready-made animation clips
A Generic / non-Humanoid rig structure
Wyvern anatomy with two hind legs and wings functioning as the front limbs

For the first step I have prepared a list of 26 specific dragon animations that I need for the game.

I have two questions:

1. If you use my existing 3D model, which animation package/service would I need to purchase from you to create all of these animations?

2. If you create/design your own dragon model and also create these animations, which package/service would I need to purchase? Since this is going to be a mobile game, basic details would be sufficient for now.

The final animations will be used in Unity, so I would need the animations to work correctly with my existing Generic rig setup, or with the rig of the dragon you create.

You can find the list of animations in the attached file.

Thank you!
