I wish I had some enterprising neighbor teens willing to do some yard work!
Also to crawl under my house and fix the insulation.
As I get older, I would love for someone to deliver some kind of food other than pizza and chinese.
Teach old folks how to do email, FB, photo sharing, other computer tasks?
The post office now has a post card delivery ad program that allows a mailing to everyone in one zip code, so that would be the best advertising.
