No way am I clicking on Scout's link. And Scout, I said male escort, not stripper.
Yeah Scout... there's a difference.
Mrs. Smith's idea is a good one. Something you control yourself where it's only you > customer, and it's the only way to guarantee that you can say "Hey, I've got to work late on Thursday, is it okay if I come over on Saturday instead?"
Mrs. Dual does kids, infant, and family photography part time, and she can schedule everything around my job, and the kids being at school.
The idea to do combined security consulting could be a very good one. There are good COTS security systems and cameras/DVR's that can be monitored by the homeowner themselves over their iPhone or Android etc. Someone capable of upgrading their own PC, and installing a light switch or fixture can do a pretty good system.
You can point out the fallacies of a monitored service and their limitations. People are very leery of the long term commitment to a monitoring service to get a security system. A higher up-front fee that's one time for a setup they can monitor and decide if they want to call the police (and avoid false call fines) would be really attractive to lots of people. And you can draw on us for help and advice until you get your feet under you.
