React-Native - Django Rest App: Adjustments, bug fix and new features

Dear developer, We have a marketplace app for small vendors. We need you to finish a list of small adjustments, include one feature and fix bugs in our React-Native App. Here goes the list: New feature: 1 - Shopping cart feature 2 - Search bar inside the vendor store. Adjustments React Native: 1 - Change a route navigation on a go back button. 2 - Enlarge a product image on click and show the 2 images that a product have. 3 - Include a minimum sale amount to order when the vendor is registering. 4 - During product registration, if a product is Clothes category, show multiple checkbox for sizes options: small, medium, large and x-large. 5 - Login screen change "Usuario" for "Email" 6 - Consumer card show nickname instead of name. 7 - Vendor map needs to be the same as consumer map. Consumer is a custumization of gale maps. Bugs: 1 - From Menu > Perfil > Add profile picture -> the result is an infinity loading. But from Vendor Registry > Add profile picture -> the picture gets sent to the server and it works fine. 2 - error 500 when a consumer wants to reset password. You need to let me know how many hours do you need for each task or a combination of them as some are less than a hour long. Thanks.
