There are a few dropshipping companies who are reputable and reliable however they already have many, many people selling their goods, some of them on a very large scale so without a massive capital investment you would be unable to compete with those established sellers.  That would leave you at the mercy of the tin pot outfits that start off doing everything right until you increase your spend with them then the goods stop arriving wit the buyers and low quality goods are used then guess who has to refund the buyers without any hope of getting your money back from the dropshipper.
