Hey John,
I think Boyd touched on the "motherlode" for this type of business -- home delivering restaurant meals.
Back when we used to live in the (gasp) CITY, we had some filthy rich neighbors who were always building new additions and garages for their Indian motorcycles.
He worked as a contractor. SHE owned a restaurant meal delivery service.
SHE made twice as much as HE did, and she didn't mind telling anyone who asked.
She simply made a deal with local restaurants to purchase food at I believe a 15% discount, which she (or usually, one of her drivers) would pick up and deliver to the customer, tacking an additional 30% onto the restaurant's retail price for the service.
She advertised with flyers, brochures & in the newspaper. Several restaurants also displayed her brochures next to their check out.
She offered every type of food from just about anyplace that did not already deliver, and had several drivers "on call" to help get things where they were supposed to go. I believe they also called ahead to restaurants to have the orders waiting when the drivers arrived.
I suspect this service would work -- very well -- in any upper middle class urban area. Good luck!
Best Wishes,
Jim Erskine
