Don't mean to but in but is that somethin that an average joe like myself could do?
yes as long as you understand basics - hot, common ground - and you have an existing open on your main breaker. I AM NOT a licensed electrician so this is not advice, but this is pretty simple stuff.
make sure you get the correct gauge wire - for 20amp i think that is 12/2.
All the metal on your panel is safe to touch BUT DO NOT TOUCH any bare copper coming out of black or white coated cable (bare copper is ground and you can touch it.
Run the wire from your panel to the first outlet. If nothing else you can look at all your other breakers common ( NOT STOVE, DRYER, WASHER, OR AC) breakers and put white, ground (bare copper), and black into the breaker like those!!! IF you want a second outlet on that circuit just a daisy chain from the first one. there are some pretty simple options to switch over to gen power if you go manual option.
I used this

Or you can add a battery back up which will go on automatically but you either need to spend a lot of money for one big enough to power everything for any amount of time or limit what you connect!
If you want it automated it might be beyond your comfort level as you have to understand schematics and wiring diagrams and if you get it wrong you can toast the circuit and possibly your whole panel (though not likely).
