Unity Game Development with Realistic Graphics

I'm looking for an experienced game developer for a Unity game project (Android and iOS). The game will have a concept similar to Rodeo Stampede, where the character runs, collects power-ups, and dodges obstacles and enemies.

Key Gameplay Mechanics:
- Jumping over obstacles
- Dodging enemies
- Collecting power-ups
- Collecting objects
- Regular targets to achieve

Target Audience:
- The game should be appealing to everyone. So, it needs to be simple enough for kids to enjoy, yet engaging for adults and teens.

Visual Style:
- The game should have a hypercasual visual style like subway surfer. This means that I'm looking for high-quality and immersive graphics that bring the game to life.

Ideal Skills and Experience:
- Proficient with Unity game development
- Experience in creating games with similar mechanics
- Strong background in developing games for multi-age audiences
- A portfolio demonstrating previous game development work (especially with similar gameplay elements and target audiences) would be highly appreciated.

Note: Developer should know different APIs and game pre-registration on both Playstore.
