Advanced Combat System Development in Unreal

I'm seeking an expert in Unreal Engine to craft a sophisticated combat system akin to 'Bully' and 'Sleeping Dogs.' The system should feature:

- Advanced Grabbing Mechanics: Allowing either the player or the enemy to seize their opponent allowing them to do a number of different attacks like throws, hits, using environment, or putting them in different grab positions like pined on the wall or ground .
- Continued Punching Sequences: Enabling relentless strikes after a successful grab or hold button and do one big strike.
- Pinning on Wall/Ground: Providing varied combat scenarios and strategies.
-Multiplayer ready: Everything replicated.
- Easy customization: User friendly easy to add or take away attacks.
-Aerial attacks: Being able to launch or throw foe in air and hit and grab them while in mid air. -Advance locomotion
-Full gamepad ready: All of this must be on the controller and ready no mechanic missing from controller. -This intricate system must be multiplayer ready, ensuring seamless interaction and engagement.

In terms of animations, I desire a realistic style that mirrors real-world physics and combat dynamics. The ideal candidate should have a strong background in:

- Unreal Engine: Extensive experience with this game engine is a must.
- Combat System Development: Proven track record in creating intricate and engaging combat mechanics.
- Realistic Animation: Ability to develop high-quality, realistic animations.
