Xamarin - Alfa apps development

I need an Alfa prototype of a pair of two apps in Xamarin that will work together. 1st App description -> First-time lunch will show a QR code scanner, after scan a QR code (paper QR code, I will send an example later) it will need to perform a restful post to a mock-up API (this fake API can be mocked up into the same code just to simulate the action) with the data that was scanned, and with the data result from API, it will render on UI some fake data (example: Company name, address and a logo picture) and produce a new QR code (this QR code needs to include in it an ID that came from the API post result) on screen. After first-launch, this app will always render the same result with an option to scan another QR code again. 2nd app description -> This app will be installed on another mobile, that will just scan the QR code generated after API post-call from the 1st app (scan from mobile screen), then will post this data to a mock-up API and generate a fake report for now (this report can contain any fake data).
