Indian Bolt & Uber Eats Riders in Berlin - Working Conditions

Looking for Indian Bolt-Workers for a documentary Hi, my name is Luca. I am studying Screen-Based-Media at the BHT in Berlin. For my 4th Semester i want to make a short documentary about Indians living in Berlin. The focus is on delivery services like Bolt and Uber Eats. The questions this Shortfilm asks are: How are the working conditions? Why do so many indians or people from culturally indian influenced country end up working there? With what dreams did they come here? Why cant they find a better Job? Racism? Language barriers? I am still looking for a person the documentary can focus on, maybe you know some one or have an idea how i can get in contact with some one working at such a company. We would shoot the film in 1 or 2 days and there could be a small compensation. I am looking forward for your answers, or maybe you think this is a stupid idea, then i would like to know that aswell!
