My friends and I are thinking of opening up an online store like  Etsy. Like me, they are also crafters and we would like to sell quality handmade items like crocheted blankets, unique painted glasswares, etc…  any ideas how much the startup costs would be? We are also planning to turn the store into a full time gig, so we will also be needing payment gateways soon. How do we set up online credit card processing? Any help would be greatly appreciated.
