Procedural Animation for FPS on UE4 Blueprints

I need a freelancer with blueprint/unreal engine 4 coding knowledge to assist me with an FPS game. I need help with procedural animations for the first person character arms on every weapon (there are 16 weapons). And example of the animations can be found in this video: https://youtu.be/YYVEHk_KurY
It’s a multiplayer game and everything needs to replicated.
