Looking for computer tech to cover for me while I’m on vacation

I know this is a repeat of what I posted in August, but I’m still in the same boat.

I do some consulting on top of of my full time job. I perform break/fix hardware, small-network type service. I have a handful of regular clients, mostly small businesses.
Almost all of them are located in Manhattan, a few in Northern NJ. Seems that every time I go on vacation something comes up.
I’ve been gotten away with it in the past, but I’d like to have some backup this time in case something comes up. Anyone interested?
