Sorry about the pic.
Every time I try to insert the image portrait instead of landscape the insert image button gets crammed over the tinypic.com hot link and won't allow me to insert the pic
Did this a couple weeks ago. Super easy. Anyone that can do even the most basic wiring and can follow simple instructions can do this.
This model was around $400. It was a kit, prewired, remote outlet, and 10 ft 240V cord for genny.
I already ran the wire for the remote outlet to the eventual box last summer when I was running a dedicated line to my shed.
Took about three hours, but was real simple. My panel is small, which is what took so long. A lot of additional wires to cram into a small area.
Basically all you do is hook the neutral and ground from the switch to the ground bar in your panel. Then remove the wire from a current panel breaker, add the desired wire from the switch to that breaker, and wire tie the old breaker hot wire to the hot wire that corresponds with the wire just added to the breaker. Repeat as required for your generators ability. Basically all you are doing is running the power from an panel breaker and sending it to a breaker in the switch (via the wire nut) and then the power loops back to panel breaker. When you need to use that breaker during an outage switching the transfer switch from line to generate kills the loop and sends the power via the transfer switch. All the wire are labeled, so it very simple.
You can then exercise your genny by switching as many breakers from the transfer switch as required to adequately exercise the generator.
Finally.....and I was all stressed out over finding someone to do this.
