TLDR ON BOTTOM!

i’m trying to find an RCM jig and payload injector dongle in person, I can’t order it off Amazon because I’m trying to finish paying off my AC unit i bought not too long ago, its going to take a while, and i would prefer to get it in person, just because the return policy is way quicker, i like seeing peoples face as i buy, if i have questions theyd be able to resolve them there, and i like to compare, and/or see it as im buying it to make sure itll work, i’m trying to get Tomodachi life mods (living the dream) because I reaaallllyyy can’t draw, and itd be a huge life saver if i could just import images and edit them instead of having to draw the object manually myself, i believe my switch is a switch 1 from mid 2018, i dont think its patched, but let me know ive attached images, and info on the switch. also ive heard that the PC method is not best portability, and cannot load the mod without access to the PC, but, the payload injector dongle is portable,and id like to know if thats true, if so does it require internet to load mods? i dont always have access to my PC, and/or internet, im almost always out and about, i dont stay at one place, and usually drive or get droven longer distances, and i enjoy playing on the go in the car (while im not driving dw, im safe), Id also LOVE to mod my switch for obtaining FREE games such as, date everything, pokopia, stardew valley, taiko no tatsujin and animal crossing how would i go upon searching for these games for FREE , which websites are recommended, what fake websites that contain malware are there, how to tell if the file has malware in it or is a scam website, does it play the same and have all the same features if not what differences are there? what are the required steps/files, or features on your switch to download the games to the console from the internet.
i also need storage so my nintendo doesnt get laggy, or doesnt let me proceed in the game/install, so which memory card would u recommend me getting in regards to the games i want, tomodachi life mods, as well as custom backgrounds, which size in gb? the approx gb for the games i want (i’m unsure how reliable this information is, as i did a quick google search) is ~68gb.
what is the best place to buy cheaper memory card with larger storage, i dont know which software im going to use to even just to jailbreak it..

Im in a financial predicament that i wont go into details about, but its kinda hard rn trying to pay for rent, food, and just the necessities in general, if i had money to buy my games i would, buts its SO expensive, bc have you seen the prices??? pokopia 79.99!!!? for a freaking pokemon wannabe animal crossing, i LOVEEE customizable, town-builder games it would take loads of stress off my mind, and save me 20-80$ PER GAME. (which is absolutely insane)

TLDR:
I might i have a switch 1, from mid 2018, unpatched,(check images) and I want to mod it. is the PC required to run mods for the PC method? if it is required, is the payload injector portable, and does the dongle require internet to load my downloaded mods, which software would i use to download mods, and games to my switch? Is my switch patched? which websites are best for FREE games, and mods/tomodachi pngs, does the downloaded games from the internet have the same features and gameplay as the original bought version, whats the requirements to download games from websites on PC through the payload injector, and which memory card should i get based off of the games i want + tomodachi mods and custom wallpapers?

i apologize if i asked the same question multiple times, or sounded dumb i just want to figure this out, i tried watching youtube videos, but they dont go into depth about the information its just a tutorial on how to jailbreak it, and id prefer for other people from different sources give me information, i might need an explanation on something, im aware of how to jailbreak it, im just not aware of the knowledge behind it.
