Unity Mobile Police Radar Patrol Game

Hi, I want to customize a Unity car chase template into a mobile police radar patrol game. I will provide the Unity template. I want the game to include these features: 1. Police car system - Add a police car as the main player vehicle - Add police lightbar on the roof - Add siren button - Add horn button - Add lights on/off button 2. Easy and Hard control modes - Easy mode: auto gas, left/right steering, brake, siren, lights, horn - Hard mode: manual gas, brake, steering, handbrake, siren, lights, horn - Player can choose control mode from settings 3. Radar system - Police car can detect traffic vehicle speed - Show target vehicle speed and road speed limit on screen - If a car is speeding, mark it as a violator - Player can start a chase after speeding is detected 4. Parked radar mode - Police car can stop on the side of the road - Player can activate radar while parked - Passing cars are scanned - If a speeding car is detected, player can press “CHASE” and start pursuit 5. Chase and pull over system - Player chases the speeding car - If the player stays close enough for a few seconds, the suspect pulls over - Mission completed after successful pull over - If the suspect escapes, mission failed 6. Coin reward system - Player earns coins after every successful mission - Coins are based on mission difficulty and performance - Bonus coins for no crash, fast arrest, hard mode, lights/siren active - Ads should only give small bonus coins, not too much 7. Upgrade system - Player can use coins to upgrade police car speed, acceleration, brakes, tires, radar range, siren power, and lights - Free light should only be the roof lightbar - Additional lights should be unlockable with coins: - Front grill lights - Rear window lights - Front bumper lights - Rear bumper lights - Side mirror lights - Undercover hidden lights - Full emergency light package 8. Siren upgrade system - Basic siren free - Additional sirens unlock with coins: - Wail - Yelp - Hi-Lo - Air horn - Pro police siren pack - Stronger sirens should make traffic react better 9. Garage system - Player can upgrade car performance - Player can buy light packages - Player can buy siren packages - Player can see locked/unlocked items 10. Ads / monetization - Add AdMob rewarded ads - Rewarded ads should give only small coin bonuses - Add optional “watch ad for small bonus” after missions - Do not make the game pay-to-win or too easy with ads 11. Mobile build - Make Android APK build - Optimize for mobile - Fix bugs - Make sure the project is clean and editable Please give me a fixed price and timeline. Also please split the work into milestones. I do not want to pay everything upfront. Someone capable of doing all of this, please give me a price quote.
