“Store multi photo booth” – Web service / API

I’m looking for a web service / API for a “store multi photo booth”.

I am a frontend developer and I want to create a project to integrate with my online store and app for my client store.

I need a freelancer that recommends me the right hardware I should use (cameras, and another hardware like raspberry pi, etc.), and should be capable of developing this web service project.

My client wants 3 cameras on their store connected by a wifi and when a user picks the specific camera QR Code through my APP, he can take as many pictures as he wants in a certain time like 30 to 60sec.
Meanwhile another users can control the other 2 cameras at same time.

This web service should Identify this session with an unique ID and saves that fotos on a folder up to 48h. After this the user will be able to buy each photo in my app / online store.

This project will be divided in 2 parts.

Part 1 – Briefing and Freelancer selection – Project Specifications.
Part 2 – The Project. – I WILL CREATE ANOTHER PROJECT FOR THIS PART.

This project should be secure (this is very important) and with a good performance.
