So I'm going to start a multi vendor marketplace in a niche I am very familiar with. I am wanting it to be free to set up your store and make a little bit off of each sale and also have an ebay like auction house integrated into the site. What should I be researching and learning about? What are some things I need to know but probably wont think about? I am not really in a rush to get things started, but I do want to get a minimally viable site up to work on. After looking at the hosting providers, it seems like a shared server would be ok for now, but is that ok for what I am trying to accomplish?
