Sounds like you should create an app called Cleanr. Quick before Uber takes that idea as well (noticed they're getting into food delivery now as well and taking a large cut from the actual price of the food and a fee from the drivers part for this service which is basically just connecting drivers to restaurants and fast food chains).
Yep, these large players are taking it all - which is why I think something at the local level would do okay as an alternative. Tailored DAO that can be applied with locals in mind.
Good idea indeed. These days food home delivery is popular specially in occasion. Ubar is also available here and it seems available world wide as blogger belongs to Finland.
What you said is right.
