@LemonySnaket (no worries about the ping btw, i don't mind ^^)
I'd definitely recommend setting up a shop! It's not uncommon for people to have more than one shop, so as long as you can keep track of orders (spreadsheet maybe?) then it should be fine. Unfortunately I also don't know how to price things, but like another person said, looking at other lore shops is an option. It could give you pricing ideas as well as how to organize/lay out your shop!
