Build a React native app for iOS and android

Hey all, I need a someone who is reliable to build an app in react native for me. This app will allow gamers to play for money/prizes against other gamers. I am trying to compete with this company: [login to view URL] Please study their app and website before getting back to me. In theory the app should function as follows: -login screen -register screen -create your profile screen -Main page - shows you all available games to join and play now for money, games should range from NBA 2K22, Call of Duty - Kill Race, Madden, etc. We would ideally display the most popular games on this screen. Once user presses which game they want to play, we would show them a range of money games registering players. ($1, $5, $10, $25, $50, etc.). Once registration fills and match starts, a new game would automatically be up for registration in the system. profile screen - follow profile button; basic info about you; displays your followers; shows your followers count; show your top stats/ win amounts create custom match - you set the rules; for tournament creators; select buy in amount, including free search - allows users to search for tournaments that they can join based on certain filters such as game type or tournament name ****This system should be fully secured in terms of its database. Users will have to use their credit card/venmo/paypal to fill their wallet. Users will have a wallet that displays their balance and can cash back out to their account. ****Time is very sensitive for me here. I need someone who can work full time on this for maybe 2-3 months if not faster and bang this out. ***My budget is around 5K
