a week? how bout no....
i hate giving this speech but i like helping people out so i'll try mah best
basically, it's all about getting the hands synchronized. try just muting the strings with your left hand and just going up and down with your picking hand across the strings in a "sweeping" motion. then when you can do that (shouldnt be that hard haha) try doing two string little arps, like
and pull off on the 8/12 parts
down physically pick the downstrokes, its like your gliding from one string to the next.
here are some three string sweeps
you'll find theres tonssss of different patterns/ways to play different arps and sweeps and its pretty easy to figure them out, like all the major and minor will be the same position/fingering but just different frets etc. honestly it took me forever and i worked a lot on it, but one day it just fucking clicked, my hands locked together and i was like yeeeahhh!!!!
i didn't really cover everything but this should be a nice start, heres some videos of me sweeping, so you can see the hand movements etc.

well this one you cant see my right hand
once i get my camera working i definitely want to make some tutorials on sweeping etc.
and those vids are kinda shit, i know. it was a while ago im definitely better now (cheap fail excuses like everyone uses)
