i need ebay va

i don‘t have any experience in Walmart to eBay DS. I‘m really interested in, especially in making 8k/month profit

What do i need to start with it ?
Is it possible to do it from everywhere?
Is it possible to sell in the USA ? But living in Germany and Not beeing an american?
Do i need a walmart acc or something else?
How fast is the shipping from walmart?

Best regards
