Just sell some stuff. You can start right away. Look for some old and won't-be-used stuff in your home. This way you will clean up some space and others will benefit from your stuff. You will have more room for your new stuff and you will earn some money to buy the new stuff.
So instead of looking far away, why don't you just look inside your home and sell the stuff you don't really need? This is really quick and you can earn money without having the initial money. You won't need to deal with a supplier, with the logistics, with the pricing and with the profits. You just pick up the things and sell them. You set the price way below the cost of the brand new one so that someone would buy fast. You can also make the old new again through some tweaking and cleaning. Then you can sell the items at a relatively high price.
To make money, you don't need to think hard and become so creative. You just need to know where to look and how to sell the items fast.
