iOS demo app for Product Catalog and barcode scanning

I need a demo build for an iPhone in order to raise funding for a business. The app needs to add products to product catalog/database, show a list of products in the product catalog, and show an individual product when an item is selected from the product list. To add a product, the user must be able to scan a code-128 barcode and store the number into a Barcode field, takes a picture of a product, and allows a user to enter text into three fields (Name, SKU, Price) and then store all of that information on a local database on the iPhone. I also need a screen to show a list of all of the products on the database and one additional screen to show the details of a product. The app can have a splash page that shows our company logo. Bottom navigation buttons could be Home (splash page), Product Catalog, Add Product. On the Add Product page, there will be a Scan button to click to activate the camera for scanning the barcode. Once the barcode is scanned, the barcode number will populate the Barcode field. Then text fields for Product, SKU, and Price. Then an Add button to save the product to the product catalog. After selecting the Add button, the user is returned to the Product Catalog page. The product catalog page should display the Name and Price fields only and should be sorted from most recently added first. Upon selecting an item in the list, the Product Detail page should open and display the image of the product, the product Name, SKU, Barcode Nbr, and Price. There should be a back button to return the user to the Product Catalog. Please let me know if there are any questions. This should be straight forward and mostly native iOS functionality. I don't expect this would take more than maybe 20 hours.
