There are quite a few things that need to be done to be successful with drop shipping.
1. Find legitimate suppliers, this can be difficult because it's hard to tell who is and isn't a real drop ship wholesaler. Your best best it to sign up for a directory that has thousands of different suppliers. Real ones cost money, and are not free.
2. You will need to research different products, your market, and your competition. Don't get too attached to the idea of selling a particular product. Electronics for example, everyone like them but they are nearly impossible to be profitable with drop shipping because of the competition and low margins.
3. You will need a website. But websites that offer you a premade website with a short lists of products for you to sell are ALWAYS a rip off. There are services like Shopify.com or Yahoo Stores that make it easy for those without technical skill to build a webstore easily, so don't worry.
Hope this helps and good luck!
