i have worked on shopify , i can create a store as well as teach you how to use the store and if you have idea on what product you want sell i can help you where to market you product ,who will buy your product , on which audience you should focus more using audience insight .
i will help to create store + customize store+will help to write payment policy , terms of condition , privacy policy and also refund policy + buy domain(will be separate 650rs from godaddy or other source ,buying domain from shopify is costly instead we buy from other site and connect to shopify ) + store webdesign + on which audience to focus so that your product will sell faster . This much i can do within 3-4 days after this the main task is to put the product in the store for which it will take some more time because we need to explain the details of each products
