complete started react native app

I have a app that was created in expo react native and the previous coder did not finish the project, i have the code and its about half done . The app uses the same database as the website so so if you sign up on the app the website will be the same. take a look at the code let me know please only bid on the cost to complete . don't bid 50 then ask for 2000 to complete it.
----
main screen will have the list below working - ( typical CRUD operation) also will need to create webhook pages on main website for each.
