I started with Dropship CEO (you can download it free, just Google it) and a FB group called The Amazing Seller.
But, let me tell you, it's not easy if you don't have the budget. I invested a couple of thousand dollars to fail miserably, since I did not have a budget large enough to compete with high ad clicks.
On top of that, when I started, I picked a product with little competition and in a month or two, more people with more money came in and all I could do is sell the product below cost to get rid of the inventory and move on to other things with a huge hole in my pocket.
