Build me a video game app

I’m looking for someone who can help me build and design an ios software application. The app needs to be a video game app. I need 3 different play modes, the concept needs to be similar to PUB G or call of duty. However, customized to meet my needs. Budget is $300-$700. Please only reach out if you are able to adjust to that price, and truly help with the creation. Take a look at the file for a better idea.
