How to drop ship with a business?

Ok, so I am 15 and want to make money online with drop shipping. I have done some research but am still confused. I understand i have to set up a store on ebay. But my questions are do i just post something on ebay from amazon but put it for more and if someone buys it i buy it form amazon and send it to them. Or can you like team up with a company such as Amazon and they will help you drop ship and save you money. Any help would be appreciated.
