Let's say I have a friend who owns a factory and makes rings and necklaces according to my unique design (1000 pieces order minimum). I want to sell them strictly online, and I'm sure that I won't be making more than $100,000/year, possibly not even $50,000/year (I don't want to open a massive store chain or something like that). I would be using Kickstarter or something similar for fundraiser to start it up. Do I need to start some sort of a company for this, or can I just sell them and pay the taxes myself by the end of the year? It would be a lot less messy if I could just accept payments using Paypal or something like that, and pay the taxes myself instead of registering a company for such a low income (for a business).
The transaction would go something like this: I send that friend of mine money through Paypal or Western Union or something like that, he makes for the ordered amount of rings or necklaces, he ships a box of them to me. I buy boxes to pack them in in the meantime, and when they arrive - I pack them up myself, then print out the addresses and take them to the postal office for them to be shipped to the customers when an order is placed. I know it's a lot of messing around, but I don't have much money and I doubt my campaign will be successful as I have zero social influence or presence.
I would prefer it to not be EU-only, I want to sell worldwide.
Let's also say that I live in Sweden or Norway, but I'm not a citizen here, instead I'm a citizen of Latvia.
