It always slows down this time of year.
If you can find a way to get into government facilities, military bases, contractors like Raytheon, Lockheed, etc, they tend to dump money this time of year so they don't have their budgets lowered.
They are very hard to get in and a PIA to bid, invoice, etc, but they have work and the money to pay for it.
We do this kind of work out of our special projects/service dept. And we just landed a few jobs with Raytheon. Some large private companies dump money too. AT&T has us bidding like crazy for work to be done through the holiday months.
I don't know how anyone can survive on just resi right now in this economy.
I would think that resi service has to be slow during the holidays, unless forces of nature create some emergency work.
