Unity Advanced 3rd person controller for melee combat

Hello all,

I am a CS and game design Junior trying to make a hacknslash Unity game in my free time (inspired by Dynasty Warriors 3). I am having some trouble finding the right way of combining root motion anims, with the physics system.

Here is where I am at so far: https://youtu.be/9vhtj_Jwics (Ignore the Quaternion errors as I was trying to move some rootmotion calculations over from OnAnimatorMove to FixedUpdate)

I was trying to implement IK and I had to convert my generic avatars over to humanoid, and now I am experiencing many root motion issues. Additionally, I am having a hard time getting arial juggling to work like in DW3. I am also looking for solutions to knockback collisions (currently changing layers when airborne otherwise characters set "isGrounded" to true on others heads), how to implement blocking properly, blend layers for strafing while blocking, eventually adding sync kills (Like shadow of mordor/Assasins Creed) and other general advice on how I could improve this setup.

So what I think I need is a programmer or tech artist familiar with advanced 3rd person character controllers, root motion, and unitys physics system.

I want to compensate whoever decided to help me, however, I am a student and hope to negotate a realistic rate I can afford.
