Realistic Multiplayer iOS Game

I'm looking to develop a multiplayer iOS game similar to COD's Prop Hunt. The game should feature realistic graphics and include the following modes:

- Team Deathmatch
- Free-for-All
- Capture the Flag

The game will be played from a third-person perspective.

Ideal skills and experience:
- Proven experience in developing multiplayer iOS games
- Strong portfolio in realistic graphics
- Expertise in game mechanics for TDM, FFA, and CTF modes
- Proficient in third-person perspective gameplay design
- Knowledge of iOS game deployment and optimization

Please provide samples of similar work and estimated timelines.
