Nice idea.
A few similar such services exist - each in their own city/state - but each service is usually for a few specific services (like getting your packages or laundry, selling your property etc) - I don't know of any platform that combines all such services...Fiverr would be the closest perhaps.
the only risk here - or issue that would need to check - is if this service has a need in 'regular' times, when the Corona passes in a few months.
Good luck
