Need Feedback- Personal Shopper and Conerige Service in India

I am based out of Mumbai. My own married sister lives in the US. She has always been ordering stuff from online portals here in India to our address (clothes, food items, returns gifts, etc.) and my father combines all of it together and ships it to her address via DHL.

Apart from this, I have also seen people worry about errands back in India.

Is there a need for personal shopper service in India who can collect parcels on your behalf/go to shops offline and procure things as per your requirement and ship them to USA for you? Or maybe a virtual assistant or a concierge sort of service for offline errands?

Thinking if there is demand for such services and if it can be a good side hustle for me since I have done it previously for my sister.

Any inputs from Indian community in US appreciated!
