You can try dropshipping. That way you won`t need to store any goods. And you can find many sellers from who you can buy in bulk at cheap prices
goodluck mate
dropshipping will only make you gaining a little profit rather than producing the product yourself,and if I were OP I would prefer selling a digital goods than a physical thing due to cost of shipping and etc,selling digital goods will make you getting pure profit and not being cut off by the shipping cost so it's really worth it
