Complete my "React Native" app

I have a react native app to sell some crypto currencies to local people. I almost did all the screens so far and some backend, etc. so just need some react native work to send and receive data from/to back-end API which I don't have time to finish it + some small issues on the app screens. Here's what I need: 1- Signup (screen was done backend is ready) Work to do: validate fields and post to back-end and receive the API result and show (error or success) 2- Login (screen + back-end was done, post to api was also done) Work to do: validate login info and show results after api call (redux was also done and you receive json from back-end) 3- Netinfo Connect check (it's done but need for all screens) Work to do: simply add it globally to check in all screens that network is connecred otherwise show error message 4- Upload 3 Docs Images (screens are ready) Work to do: Simply send those images to API and receive the result and show to user (like upload completed + those 3 images) 5- Update Profile (screen is ready) Work to do: post screen data to API and show update message and update redux store (redux is almost ready to save user data) 6- Loading animation Work to do: whenever send or receive fom backend show a loading animation somehow 7- Push notification (nothing was done) Work to do: use "Onesignal" push notifications to rceive notifications from admin 8- Buy Currency (One screen is almost ready will provide 2 more screens) users see the product page and see the currency price etc. there are 2 textboxes and user can convert 2 correncies together (need js code), calculate and then add to basket to buy. get wallet info and NO need to make payments online. payments were already added to user's credit. simply get user's credit from API and send amont of currency to API and it will make the payment. Show the results. My budget is 200 AUD and need to be done in less than a week. Will pay 50 AUD to change this to an expo project (which is 1 line command! but need to check all work properly in android and ios) I'm a Reat Native Dev and can spend an hour a day to help you do it faster.
