Great idea.
The only person I know of is someone (a licenced contractor) who does an excellent job of renovating fixeruppers.
I'd be more than willing to donate on a per job basis (costs only) for senior citizens on a meager pension (minor carpentry, screen doors, plumbing leaks, small electric jobs, setting up computers and VCRs, advice on products to buy, and my specialty, free coaching on completing ones relationship with parents, spouse/children.
