I can teach you how to start being a successful seller on eBay and I can go much more in depth if youre interested in opening a store. I was an ecommerce manager for a very successful company for a while before I left to pursue other avenues. I can do take you from zero knowledge to professional depending on how much time and energy you really want to spend learning. I will do a half hour of consulting for 25 points, however i will tell you that you will need much more than a half hour to take in everything you need to know.
