Delivering Groceries to the Elderly

I have 2 questions:

1. What would be the best way to market this service? (I was thinking flyers on church bulletin boards...but what else?)

2. How much should I charge? (I'm in a middle-upper class area of New England.)

I was in a used bookstore thumbing through the business section and I found this amazingly simple little idea in an ANCIENT book of 'work from home' ideas.

In fact, I've been finding a ton of great business advice in OLD books. So much "new" stuff seems to be rehashed, codified, acronymed versions of the same material.

Thanks for any input.
