Unreal Engine Game Animation Design

Hi there,
I'm creating a videogame based on Unreal Engine 5.6 since one year with a little team of volunteers. We have done many work on physics system, gameplay, level design, clothing system by ourselves but character animation is a nightmare for us and we didn't spend time for that.
In order to improve our game we are looking for someone who can create animations and deliver as ready to import. We are using AI for 3d asset, code and other things, we don't care if you are using AI too, to be honest I'm working 4x more than before AI and our project couldn't be at this point without this help...
Right now we are using default animations from 3rd person project (forward/back/jump) but we need more :
- left and right move
- crouch
- sit down
- mining animation (hold a laser tool with both hands) focusing a point where the player is looking for
- bend down to pick something up off the floor to store in backpack
- pick up and carry a jerry can in each hand

And this is just the beginning, we are looking for a long term cooperation. We will start with a fixed price project but in the future we will work with hourly rate.
Kick off : as soon as possible but we are very flexible, animations are not an emergency at all but an improvement we have to do by 3 months
