Build an Online Store

I want to make a website similar to [login to view URL] where people can upload, swap, or sell their own used/or new craft supplies. I want it to also include a forum. I want it to essentially be a thrift store online that will attract crafters and also have a clothes component. Very similar to vinted where people can create a profile, list products, where people can ask questions about, like, ask to swap, or buy. There also needs to be a component where people can communicate with each other (over messenger).
