It is always slow at this time of the year, it will pick up in a couple of months.
I would not even entertain an idea of "Certifying" a home as being OK.
NACHI started a program like this and Nick says that the inspector has no liability as the home owner is the one that is Certifying the home! I'm sure Nick will go to court and tell the judge and jury this as well!
Anyway, I don't see it as a way to increase business. When you think about it the buyer if they have any sense will get their own inspection. Now from the standpoint of prepping a home to put on the market, a pre-listing inspection is helpful.
