Integration of API in React Project

Hi, I need a react developer to add few functions in my react js project. Step 1: The user will create an event(invitation) from its dashboard after login and add 2-3 banner/images (can be sponsors or event related with URLs on click) from his account. Step 2: Event creation request will be sent to admin where admin will accept the request and edit the request with an embed code. Step 3: After approval and addition of embed code by admin, the above event will become a shareable URL in user's dashboard which he can copy or share on various social media platforms. Step 4: Any person who opens the URL will be asked to enter the access code or join the event. On clicking join event, he will be redirected to the payment page where he will make payment and a unique access code will be sent to his given email. This opened page will also show timing of event added by admin and banners of sponsored companies. Step 5: Admin will be allowed to mark registration of event as "disabled" from admin panel after end of event. So, he can avoid people to use previous access code or make payment. I want it to be done in 2-3 days max. My budget is $100 and payment gateway integration will be paypal or stripe, I will tell about it later and it will be a separate milestone of $50. Only apply after reading instructions carefully. I will report those who ask me questions without reading the above instructions.
