Seniors who babysit?

Curious if anyone knows of seniors/retired people-or an appropriate organization-that might be interested in doing some childcare/mother's helping?  We are looking for in-home help in the mornings for a couple of hours two-three x a week, totalling 7-10 hours, and will be home most of that time.  Thinking that the early hours and low # of hours might work better for a retiree than a pro nanny or sitter.

Thanks!
