no electrical power to outlet
Probably the most useful thing you can do is to get a young volunteer from church who is willing to crawl into the attic while the electrician volunteer stands below the hatch or whatever. The electrician tells the crawler what to do and the crawler tells the electrician what the crawler sees. 

The protocol for reducing the hazard of this procedure is patience. No matter how much they yell at each other, the crawler must think before each step. If anybody feels unsafe at any time, everybody stops and you call a professional.
